In 2009, in the non-award winning series Toy Stories, | 0:00:02 | 0:00:05 | |
we built this, the world's biggest Airfix model, | 0:00:05 | 0:00:09 | |
the legendary Supermarine Spitfire as a full sized construction kit, | 0:00:09 | 0:00:15 | |
scale 1:1, and we're very proud of it. We really are. | 0:00:15 | 0:00:19 | |
It does, though, have a serious shortcoming, | 0:00:19 | 0:00:22 | |
the one shared by all Airfix models really, which is that it only actually works in the imagination, | 0:00:22 | 0:00:27 | |
held out at arm's length or maybe dangling from a piece of fishing line from your bedroom ceiling. | 0:00:27 | 0:00:33 | |
It doesn't really fly. | 0:00:33 | 0:00:36 | |
This, however, does, | 0:00:36 | 0:00:41 | |
and it's given us an idea. | 0:00:41 | 0:00:43 | |
I was an amateur aeronautical engineer from a very early age. | 0:00:57 | 0:01:00 | |
Back in those heady days of loud shirts and long hair, | 0:01:02 | 0:01:05 | |
you could pop down to the newsagents and for about 9d, | 0:01:05 | 0:01:07 | |
come away with a small self-assembly glider kit. | 0:01:07 | 0:01:11 | |
With just a few bits of balsa wood, | 0:01:12 | 0:01:14 | |
and, if you were posh, a rubber band, | 0:01:14 | 0:01:16 | |
you could hold in your ten-year-old hands the key to the mystery of flight. | 0:01:16 | 0:01:21 | |
It's a toy I've always remembered fondly, and wanted to revisit, | 0:01:21 | 0:01:24 | |
but we could never find a challenge big enough for it. | 0:01:24 | 0:01:28 | |
Until now. | 0:01:28 | 0:01:29 | |
So, if you're watching from America these are the White Cliffs of Dover, | 0:01:33 | 0:01:37 | |
very evocatively named because they're white and they're in Dover. | 0:01:37 | 0:01:40 | |
22 miles approximately over there is the nearest point of France, | 0:01:40 | 0:01:45 | |
and over there, various jumped-up little Hitlers like Napoleon | 0:01:45 | 0:01:48 | |
and indeed Hitler, have stood and looked this way and thought, | 0:01:48 | 0:01:51 | |
"We'll have that", whilst people have stood here, looked into the mist | 0:01:51 | 0:01:54 | |
which is often present, and said, "Oh, the continent is cut off". | 0:01:54 | 0:01:58 | |
Before flight, these islands were fairly safe from foreign tourists. | 0:01:58 | 0:02:02 | |
The cruel sea saw to that. | 0:02:02 | 0:02:05 | |
Shakespeare called England "a precious stone set in the silver sea, which serves it as a moat", | 0:02:05 | 0:02:10 | |
and other things a man in tights might say. | 0:02:10 | 0:02:13 | |
But forsooth, the baldy bard couldn't have imagined | 0:02:13 | 0:02:16 | |
that 300 years later all that would change. | 0:02:16 | 0:02:18 | |
In 1909 Louis Bleriot struck a blow for comedy moustachioed Frenchmen the world over | 0:02:20 | 0:02:25 | |
by becoming the first man to cross the Channel in an aeroplane. | 0:02:25 | 0:02:29 | |
Bleriot flew over and landed just over there somewhere actually, near the castle. | 0:02:31 | 0:02:35 | |
Once that happened, people must have realised the world is going to change. | 0:02:35 | 0:02:40 | |
Pretty soon, no decade was complete without a new cross-Channel aviation record of some sort. | 0:02:40 | 0:02:45 | |
There have been many more. | 0:02:46 | 0:02:48 | |
First airship, first helium balloon cluster, first helicopter, first autogyro. | 0:02:48 | 0:02:54 | |
First passenger, first woman, first letter, first cat. | 0:02:54 | 0:02:59 | |
In fact, you'd be forgiven for thinking that in the 100 years | 0:02:59 | 0:03:02 | |
since Bleriot made his flight, there would be no more cross-Channel | 0:03:02 | 0:03:06 | |
aviation records to be set, but there is. | 0:03:06 | 0:03:09 | |
We've found one. | 0:03:09 | 0:03:11 | |
First free-flight model glider to cross from England to France. | 0:03:11 | 0:03:16 | |
So that's what we're going to do. | 0:03:16 | 0:03:19 | |
If we succeed, the 22-mile flight will set a new British | 0:03:19 | 0:03:22 | |
straight distance record for a toy glider. | 0:03:22 | 0:03:25 | |
That's the best thing I've ever seen. That's just fabulous! | 0:03:25 | 0:03:28 | |
A toy glider that we are going to conceive and build ourselves. | 0:03:28 | 0:03:32 | |
Here we go! | 0:03:32 | 0:03:34 | |
But our goal is loftier and altogether more symbolic than a simple cross-Channel record attempt. | 0:03:35 | 0:03:42 | |
Our flight will achieve closure for those thousands of people who, | 0:03:42 | 0:03:45 | |
as children like me, slaved for hours over balsa, glue and paper, | 0:03:45 | 0:03:50 | |
only to see the dream of flight dashed against the beaten earth of reality. | 0:03:50 | 0:03:54 | |
But in the world of instant gratification etcetera, | 0:03:57 | 0:03:59 | |
where is the incentive to build your own glider? | 0:03:59 | 0:04:02 | |
These days flying toys are very easy to come by | 0:04:03 | 0:04:06 | |
and actually relatively inexpensive. | 0:04:06 | 0:04:09 | |
This helicopter, for example, costs about 40 quid, | 0:04:09 | 0:04:12 | |
and it's absolutely brilliant. | 0:04:12 | 0:04:14 | |
And this Piper Cub over here is made from expanded polystyrene. | 0:04:16 | 0:04:21 | |
It comes ready-made, powered by a small electric motor. | 0:04:21 | 0:04:24 | |
You simply charge it up for a few hours, and away you go. | 0:04:24 | 0:04:29 | |
What could be better than that? | 0:04:29 | 0:04:31 | |
What you have to remember, though, is that | 0:04:32 | 0:04:34 | |
when I was a boy radio control was inconceivably expensive, | 0:04:34 | 0:04:39 | |
and it was also very bulky, and it wasn't really very reliable. | 0:04:39 | 0:04:42 | |
And the little model aero engines that people had, | 0:04:42 | 0:04:44 | |
they cost a year's pocket money, | 0:04:44 | 0:04:47 | |
so the only way to have a flying toy was to make something yourself, | 0:04:47 | 0:04:51 | |
like a glider or maybe something powered by a rubber band. | 0:04:51 | 0:04:55 | |
And you spent hours and hours and hours on your model, | 0:04:55 | 0:04:59 | |
and you loved it, and then you just set it free. | 0:04:59 | 0:05:03 | |
I mean, you knew it would probably end in disaster, | 0:05:03 | 0:05:05 | |
that you'd never see it intact again, | 0:05:05 | 0:05:07 | |
or maybe not even at all, but still you released it from captivity | 0:05:07 | 0:05:10 | |
and briefly, just very briefly, it was, it was beautiful. | 0:05:10 | 0:05:15 | |
You'd invested your wood | 0:05:15 | 0:05:17 | |
and your tissue paper with the soul of a bird, and as it soared away | 0:05:17 | 0:05:21 | |
it carried with it, or so it seemed, the dream of flight that humankind | 0:05:21 | 0:05:26 | |
has harboured ever since we first looked upwards and saw the birds. | 0:05:26 | 0:05:30 | |
It was all worth it. | 0:05:30 | 0:05:32 | |
That's enough noble sentiment. | 0:05:33 | 0:05:35 | |
If I'm to build a successful cross-Channel glider, | 0:05:35 | 0:05:38 | |
I'm going to have to apply brains over optimism. | 0:05:38 | 0:05:41 | |
There are a few basics to consider, so here's a repeat of a simple | 0:05:42 | 0:05:45 | |
flight test experiment I last made in the '70s. | 0:05:45 | 0:05:48 | |
I've made four small model gliders, | 0:05:49 | 0:05:52 | |
but on each one I've positioned the wings differently. | 0:05:52 | 0:05:56 | |
So, here's the one with the swept back wings, the jet fighter design. | 0:05:56 | 0:05:59 | |
Let's try that. | 0:05:59 | 0:06:00 | |
The basic problem with that is that you need a huge amount of air speed for it to fly. | 0:06:02 | 0:06:06 | |
Jet fighters go very fast, they have swept back wings. | 0:06:06 | 0:06:09 | |
Here's the same design again, but with the wings straight out, | 0:06:09 | 0:06:13 | |
mounted at the bottom of the fuselage. | 0:06:13 | 0:06:15 | |
MUSIC: "We're Going To Be Friends" by The White Stripes | 0:06:15 | 0:06:20 | |
That had promise, but it disintegrated | 0:06:20 | 0:06:23 | |
because it isn't actually a very strong shape, nor is it very stable. | 0:06:23 | 0:06:26 | |
Here we've got the wings on the top of the fuselage. | 0:06:26 | 0:06:28 | |
They're still the same shape, dead straight and flat, right at the top. | 0:06:28 | 0:06:33 | |
That's better, isn't it? That's not bad. | 0:06:37 | 0:06:40 | |
Finally we have the wings mounted on the top of the fuselage again, | 0:06:40 | 0:06:43 | |
but this time with dihedral, that is the end of the wings are higher than the root of the wings. | 0:06:43 | 0:06:50 | |
I've also added a slight aerofoil shape, so let's try this. | 0:06:50 | 0:06:54 | |
Wait for the wind a second. Here we go. | 0:06:54 | 0:06:57 | |
THUD MUSIC STOPS ABRUPTLY | 0:06:59 | 0:07:01 | |
If we were a proper programme like Panorama, that would have worked perfectly. | 0:07:01 | 0:07:05 | |
Oh, no! | 0:07:05 | 0:07:07 | |
What did you have to stand there for, Dan? | 0:07:07 | 0:07:10 | |
Take two. | 0:07:10 | 0:07:12 | |
MUSIC CONTINUES | 0:07:12 | 0:07:15 | |
Look at that! | 0:07:15 | 0:07:17 | |
Wind's induced a bit of a stall, there, but that's flight. | 0:07:19 | 0:07:24 | |
So, a glider looks the way it does for good reason - stability. | 0:07:24 | 0:07:28 | |
We need high, slender wings, dihedral, | 0:07:30 | 0:07:32 | |
and a decent fin at the back. | 0:07:32 | 0:07:34 | |
But even with all this in mind, I still want to base our glider | 0:07:35 | 0:07:38 | |
around a real model, the sort that I might have made back in the day. | 0:07:38 | 0:07:42 | |
-Hello. -Hello. | 0:07:44 | 0:07:46 | |
Yes. I was... Ah! These are the sort of things I remember from when I was a lad. | 0:07:48 | 0:07:54 | |
The Slingsby Skylark. | 0:07:54 | 0:07:57 | |
That's the sort of shape I'm after, | 0:07:57 | 0:07:58 | |
-because it needs to have a nice fat fuselage for us to put all our kit in. -Yeah. | 0:07:58 | 0:08:03 | |
And it needs to look like the basic balsa wood glider | 0:08:03 | 0:08:06 | |
that you spent five years building if you grew up in the '70s. | 0:08:06 | 0:08:10 | |
Oh! Mm, hang on. | 0:08:10 | 0:08:13 | |
Slingsby Swallow. That's a really classic toy glider shape. | 0:08:15 | 0:08:21 | |
I like this. It's the right shape. | 0:08:22 | 0:08:26 | |
Have you got it four or five times as big? | 0:08:26 | 0:08:29 | |
Unfortunately not, no, but you'd probably find some plans. | 0:08:29 | 0:08:34 | |
Where would I get a plan from then, for it? | 0:08:34 | 0:08:36 | |
You could always try the internet. | 0:08:36 | 0:08:39 | |
The internet. Do you know, I'd forgotten about that. | 0:08:39 | 0:08:43 | |
This is perfect. | 0:08:43 | 0:08:45 | |
The real Slingsby Swallow was an RAF training glider in the 1950s, | 0:08:45 | 0:08:49 | |
so it has the right sort of stable, high wing, dihedral design, | 0:08:49 | 0:08:53 | |
and space inside for our kit. | 0:08:53 | 0:08:55 | |
After numerous unbroadcastable attempts at searching Google | 0:08:57 | 0:09:00 | |
for the word "swallow", we finally hit upon a company | 0:09:00 | 0:09:03 | |
who could supply us with the supersized plans we need. | 0:09:03 | 0:09:06 | |
And there it is, ready. | 0:09:08 | 0:09:10 | |
At first glance, this retro design doesn't seem very aerodynamic. | 0:09:11 | 0:09:15 | |
Quite an old-fashioned wing shape. It looks quite draggy. | 0:09:15 | 0:09:20 | |
That's an aeronautical term. | 0:09:20 | 0:09:22 | |
This... I suspect we may have to think about that a bit. | 0:09:22 | 0:09:27 | |
It might be a 50-year-old design at heart, but producing | 0:09:27 | 0:09:30 | |
the hundreds of balsa wood parts is a gloriously 21st century process. | 0:09:30 | 0:09:36 | |
Absolutely fantastic! | 0:09:36 | 0:09:37 | |
Now watch this. | 0:09:40 | 0:09:42 | |
That looks as if it's just been printed, | 0:09:42 | 0:09:44 | |
but in fact the laser has cut the wood. | 0:09:44 | 0:09:49 | |
There is a dimensionally perfect wing rib. | 0:09:50 | 0:09:53 | |
That represents probably an hour's work back in 1975 or whenever I was doing this. | 0:09:53 | 0:10:00 | |
Bye. | 0:10:00 | 0:10:01 | |
To make sure my rather nostalgic choice won't lead to disaster | 0:10:01 | 0:10:05 | |
over the channel, we need to see how well the swallow flies, | 0:10:05 | 0:10:08 | |
so we get a friendly enthusiast to put it all together | 0:10:08 | 0:10:11 | |
so we can test it out over dry land. | 0:10:11 | 0:10:13 | |
Dryish. | 0:10:16 | 0:10:17 | |
So here we are on a hill in Oxfordshire, | 0:10:19 | 0:10:22 | |
and this is where we find out if this design has what it takes to be a record-breaking toy aeroplane. | 0:10:22 | 0:10:28 | |
There are lots of considerations in aeroplane design. | 0:10:28 | 0:10:30 | |
They can be designed for speed or manoeuvrability or endurance, | 0:10:30 | 0:10:35 | |
or load carrying capacity. | 0:10:35 | 0:10:36 | |
I've chosen this design because it looks like one I made when I was 12. | 0:10:36 | 0:10:40 | |
So let's see if it has the endurance, | 0:10:40 | 0:10:44 | |
if it has the soul of aviation in it, to fly through this valley. | 0:10:44 | 0:10:47 | |
There's only one way to do this. | 0:10:47 | 0:10:49 | |
We've put all the work in, now you just have to throw it off the hill and see what happens. | 0:10:49 | 0:10:53 | |
-Try not to muck it up, Number Two. -You ready? | 0:10:53 | 0:10:57 | |
Happy? | 0:10:57 | 0:10:58 | |
Oh! | 0:11:00 | 0:11:03 | |
It's scaring the birds! | 0:11:05 | 0:11:06 | |
Oh! | 0:11:08 | 0:11:09 | |
It's down there. Woah! | 0:11:12 | 0:11:14 | |
Well, it's not broken. | 0:11:14 | 0:11:16 | |
HE LAUGHS | 0:11:16 | 0:11:18 | |
That's a very good result by the standards of my childhood. | 0:11:18 | 0:11:21 | |
The aeroplane is still in one piece, it's usable again. | 0:11:21 | 0:11:24 | |
That makes it a very good landing in aviation terms, | 0:11:24 | 0:11:26 | |
but it hasn't actually gone very far. | 0:11:26 | 0:11:28 | |
'So, we re-trim the swallow, removing some weight from the nose, | 0:11:30 | 0:11:33 | |
'and give it another go.' | 0:11:33 | 0:11:35 | |
-Here we go! -Go! -Woo! Look at that! -That's better! | 0:11:35 | 0:11:40 | |
MUSIC: "The Dark Is Rising" by Mercury Rev | 0:11:40 | 0:11:44 | |
Look at that! | 0:11:57 | 0:11:58 | |
Oh, caught a gust, caught a gust! | 0:12:02 | 0:12:04 | |
-No! -No, it's done it! No, it's turned back. It's good. | 0:12:06 | 0:12:10 | |
-Go on. -Ah! -Go on, go on! | 0:12:12 | 0:12:14 | |
It's not the greatest. | 0:12:18 | 0:12:20 | |
ALL: Oh! | 0:12:20 | 0:12:23 | |
It's still flying. | 0:12:23 | 0:12:26 | |
Come on, baby! | 0:12:26 | 0:12:27 | |
-Now it's down. -That's landed. That's more like it, look at that! | 0:12:29 | 0:12:33 | |
We've moved two whole fields. | 0:12:33 | 0:12:35 | |
That's already better, look, | 0:12:36 | 0:12:38 | |
that's gone at least three times as far as it did on the first flight, | 0:12:38 | 0:12:42 | |
just with a bit of tweaking of weight and balance. | 0:12:42 | 0:12:45 | |
That is the best model aeroplane I've ever been involved with. | 0:12:45 | 0:12:49 | |
That has gone... Well, every other one I've built only ever got | 0:12:49 | 0:12:52 | |
about as far as that little bush over there, and look at that. | 0:12:52 | 0:12:55 | |
It's almost out of sight. Look at it! | 0:12:55 | 0:12:57 | |
We thought this was amazing. | 0:12:57 | 0:13:00 | |
It was only when we sent our bedrenched lackeys down | 0:13:00 | 0:13:06 | |
to measure the distance that we came in for a sobering shock. | 0:13:06 | 0:13:10 | |
On that rather good throw, our glider reached a distance of 326 yards. | 0:13:10 | 0:13:13 | |
To merely scrape onto the beach at Calais, | 0:13:13 | 0:13:16 | |
our glider must cover 22 miles, or 38,720 yards. | 0:13:16 | 0:13:20 | |
That's 120 times as far. | 0:13:20 | 0:13:23 | |
Chucking it off the white cliffs just won't cut it. | 0:13:23 | 0:13:27 | |
Even throwing it off this hill nearly crashed it. | 0:13:27 | 0:13:30 | |
To stand any hope at all, we'll have to throw it from as high up | 0:13:30 | 0:13:33 | |
as we possibly can, and that means using a hot air balloon. | 0:13:33 | 0:13:36 | |
And even then, the glider will be at the mercy of | 0:13:36 | 0:13:41 | |
that most British of opponents. | 0:13:41 | 0:13:44 | |
What we can't really do anything about is the weather, the elements. | 0:13:44 | 0:13:47 | |
They are the things that nearly did for Alcock and Brown flying across the Atlantic, | 0:13:47 | 0:13:51 | |
and nearly did for the Wright brothers at Kitty Hawk and so on. | 0:13:51 | 0:13:55 | |
They could completely scupper it. | 0:13:55 | 0:13:57 | |
That is a very, very big model. | 0:13:59 | 0:14:02 | |
But it's a tiny, tiny aeroplane, and France is ever such a long way away. | 0:14:02 | 0:14:06 | |
Louis Bleriot himself was almost brought down by the treacherous weather over the channel, | 0:14:08 | 0:14:13 | |
and he had an engine. | 0:14:13 | 0:14:14 | |
And our Swallow will be doomed anyway if, as I suspect, | 0:14:15 | 0:14:19 | |
its basic design simply isn't fit for aerodynamic purpose. | 0:14:19 | 0:14:23 | |
Well, this is the R J Mitchell wind tunnel | 0:14:23 | 0:14:26 | |
at the University of Southampton Faculty of Engineering and the Environment. | 0:14:26 | 0:14:31 | |
Here is our glider, or sort of just over half of it, and we're going to test, I think, | 0:14:31 | 0:14:35 | |
for the lift drag ratio at various speeds and angles of attack. | 0:14:35 | 0:14:40 | |
Exactly. We can go as soon as you're ready. | 0:14:40 | 0:14:43 | |
-Are we ready? -We're ready, yeah. -We are go for wind tunnel. | 0:14:43 | 0:14:46 | |
-So, start fan. -Perfect. | 0:14:46 | 0:14:50 | |
What we're actually trying to discover here is the swallow's glide ratio, that is, | 0:14:53 | 0:14:58 | |
how much it loses in height compared with how far it flies in distance. | 0:14:58 | 0:15:02 | |
For example, I've estimated that to make it across the sea, | 0:15:02 | 0:15:06 | |
our glider needs a minimum glide ratio of 20:1. | 0:15:06 | 0:15:09 | |
So, for every foot it loses in height, | 0:15:10 | 0:15:12 | |
it must travel 20 feet forwards. | 0:15:12 | 0:15:15 | |
It's high drama in the wind tunnel, as you can see. | 0:15:16 | 0:15:19 | |
A one winged aeroplane making excellent, steady progress through the sky. | 0:15:19 | 0:15:23 | |
So... | 0:15:27 | 0:15:28 | |
Give me the news, doctor. Is it good or bad? | 0:15:30 | 0:15:33 | |
It's not good and it's not bad. | 0:15:33 | 0:15:35 | |
The lift to drag ratio is probably in the order of about 14. | 0:15:35 | 0:15:38 | |
It's not what you want for your long distance one. | 0:15:38 | 0:15:41 | |
-14? -Yeah. | 0:15:41 | 0:15:44 | |
-It's rubbish, isn't it? -It's not good. | 0:15:44 | 0:15:45 | |
I'm staggered that it's that bad. | 0:15:45 | 0:15:50 | |
We're going to need a better wing. | 0:15:50 | 0:15:52 | |
It's a bit annoying to discover that we'll need to design a whole new aerofoil. | 0:15:52 | 0:15:57 | |
And this problem, added to issues like the fuselage size, | 0:15:57 | 0:16:00 | |
the balloon launch logistics and the weather, is beginning to cloud | 0:16:00 | 0:16:04 | |
the simple childhood dream of flight that inspired the whole endeavour. | 0:16:04 | 0:16:08 | |
But then I hear news of a discovery in a small Devonshire town | 0:16:08 | 0:16:12 | |
that puts everything into perspective. | 0:16:12 | 0:16:15 | |
Time to set my hat at a jaunty RAF angle and investigate. | 0:16:15 | 0:16:19 | |
So tell me a bit about the building first. It used to be a school, is that right? | 0:16:19 | 0:16:23 | |
It did, as the town grammar school from about 1550 until 1910. | 0:16:23 | 0:16:27 | |
And then it stopped being a school? | 0:16:27 | 0:16:29 | |
It did, replaced by a new build in the town. | 0:16:29 | 0:16:31 | |
Right, and what was it you found? Can you show me what? | 0:16:31 | 0:16:34 | |
Well, myself and the builders found | 0:16:34 | 0:16:37 | |
-a large number of... -Oh, wow! -..paper darts. | 0:16:37 | 0:16:40 | |
-What's that bit made from? -That's a pen nib. | 0:16:42 | 0:16:45 | |
God, so it is! | 0:16:46 | 0:16:48 | |
That's amazing. How many of these did you find? | 0:16:48 | 0:16:50 | |
I think we've got about 20 now. | 0:16:50 | 0:16:52 | |
So these, well at the very latest these can be from 1910, presumably. | 0:16:53 | 0:16:58 | |
The very latest, yes, the very end of the school period, I'm sure. | 0:16:58 | 0:17:01 | |
-But they could go back to the, well, to the 19th century. -Could well be. | 0:17:01 | 0:17:06 | |
'It really is amazing to think that even before the Wright brothers' flight in 1903, | 0:17:06 | 0:17:12 | |
'children at this school were making these darts and dreaming of flight.' | 0:17:12 | 0:17:16 | |
Ow! It's a good job I had my hard hat on. | 0:17:16 | 0:17:19 | |
Hang on a minute. | 0:17:22 | 0:17:23 | |
Oh, Peter! Look at this. | 0:17:25 | 0:17:27 | |
Oh my God! Look! | 0:17:28 | 0:17:31 | |
Look here, that's incredibly exciting, look at that. | 0:17:36 | 0:17:38 | |
-Well, that's a leap ahead. -That... | 0:17:40 | 0:17:42 | |
God, I hope there's a date on that somewhere. | 0:17:45 | 0:17:47 | |
That's the classic Concorde paper dart aeroplane. | 0:17:47 | 0:17:51 | |
Wow! | 0:17:52 | 0:17:53 | |
That's amazing. Some urchin made that, well, at least 100 years ago, | 0:17:57 | 0:18:02 | |
maybe 150 years ago or more, and we used to make exactly the same one - | 0:18:02 | 0:18:08 | |
fold it in, fold it in again, fold it in half, put the wings down. | 0:18:08 | 0:18:13 | |
Do you think it would be OK to try it? | 0:18:13 | 0:18:15 | |
Oh, my word! Look at that! Did you get that? | 0:18:20 | 0:18:23 | |
That's amazing, isn't it? Come on, that is amazing. | 0:18:23 | 0:18:26 | |
That's been sitting in there for all that time, and it still works, and proves... | 0:18:26 | 0:18:32 | |
..that the pioneering flight testers were more advanced than we thought. | 0:18:34 | 0:18:39 | |
'To discover that Concorde was actually the work | 0:18:39 | 0:18:41 | |
'of an unknown 19th century child is an uplifting and emotional moment. | 0:18:41 | 0:18:46 | |
'And a quick experiment reveals that the same basic design | 0:18:48 | 0:18:52 | |
'is still in production by schoolchildren today. | 0:18:52 | 0:18:55 | |
'Children say their first word, take their first step, | 0:18:55 | 0:18:58 | |
'and then make their first aeroplane. | 0:18:58 | 0:19:00 | |
'Here's history straight down the barrel. Not quite. | 0:19:03 | 0:19:07 | |
-Oh, -BLEEP. -It went through the gap. -PETER LAUGHS | 0:19:07 | 0:19:12 | |
I've literally thrown the history of aviation down through a hole in the floor. | 0:19:12 | 0:19:16 | |
I decide to leave before I'm beaten to death by irate historians, | 0:19:19 | 0:19:22 | |
yet determined that our Swallow will do those unsung pioneers of flight proud. | 0:19:22 | 0:19:28 | |
These people are aerospace engineering students from Brunel University. | 0:19:34 | 0:19:38 | |
We also have some expert aero modellers on their way to help us, | 0:19:38 | 0:19:42 | |
and minister for aircraft production is Simmy, as you would expect. | 0:19:42 | 0:19:47 | |
So now - let's glue balsa. | 0:19:48 | 0:19:50 | |
While I've been out losing priceless historical artefacts, | 0:19:50 | 0:19:54 | |
Sim and the engineering students have been hard at work designing a new wing for the glider, | 0:19:54 | 0:19:59 | |
which should improve its pathetic 14:1 glide ratio. | 0:19:59 | 0:20:02 | |
They've dispensed with the old bulky shape, | 0:20:02 | 0:20:05 | |
and instead have come up with a leaner, meaner wing design | 0:20:05 | 0:20:08 | |
that'll cut drag and produce a lot more lift. | 0:20:08 | 0:20:11 | |
The theoretical glide ratio of the new wing is 29.3. | 0:20:11 | 0:20:15 | |
JAMES CHORTLES APPROVINGLY | 0:20:15 | 0:20:16 | |
But is that theoretical or have you allowed for the fuselage? | 0:20:16 | 0:20:19 | |
That's the problem. We haven't allowed for the fuselage in that figure, | 0:20:19 | 0:20:23 | |
and so we would be closer to 20 in reality. | 0:20:23 | 0:20:26 | |
-Really? -Close to your figures. | 0:20:26 | 0:20:29 | |
-It knocks a third off. -Yeah, because the fuselage is quite a draggy design. | 0:20:29 | 0:20:33 | |
I can't do much about that, cos we need to keep the fuselage big to get all our kit in. | 0:20:33 | 0:20:38 | |
-Yeah. -That's the problem. We're stuck with a fat fuselage. | 0:20:38 | 0:20:42 | |
-Let's say we want 30 miles. -Yeah. -To be on the safe side. | 0:20:42 | 0:20:45 | |
Can your programme calculate the launch height, assuming it's 20:1? | 0:20:45 | 0:20:50 | |
-Yes. -For us to get 30 miles, what's...? | 0:20:50 | 0:20:52 | |
It's around 8,000 feet we need to be releasing the glider from. | 0:20:52 | 0:20:55 | |
8,000 feet. Finally, our plan is coming together. | 0:20:55 | 0:20:59 | |
We now have a launch height of 8,000 feet and with a glide ratio of | 0:20:59 | 0:21:03 | |
20:1 our glider should comfortably make it, channel weather permitting. | 0:21:03 | 0:21:08 | |
But how, you may be wondering, | 0:21:08 | 0:21:09 | |
will our free flight glider know it's supposed to go to France? | 0:21:09 | 0:21:12 | |
What's to stop it sodding off to Hastings? | 0:21:12 | 0:21:15 | |
Our boffin, Dr Ben, has come up with a guidance system. | 0:21:15 | 0:21:19 | |
So, this is our autopilot. | 0:21:19 | 0:21:20 | |
So, in here we have gyroscopes, we're got an accelerometer, | 0:21:20 | 0:21:24 | |
we have a GPS so it knows where it's going. | 0:21:24 | 0:21:26 | |
We also finally, then, have this air speed sensor | 0:21:26 | 0:21:28 | |
and you can work out how fast you're going. | 0:21:28 | 0:21:30 | |
It's pointing where it wants to go. It gets blown that way. | 0:21:30 | 0:21:34 | |
It knows that because of the accelerometers, all those little | 0:21:34 | 0:21:37 | |
servers will then automatically alter the control services. | 0:21:37 | 0:21:39 | |
-Pull it back. -Turn it back on course. -Like that. -And all that is in there. | 0:21:39 | 0:21:43 | |
All that's in there. We're never going to have time to test it properly, | 0:21:43 | 0:21:46 | |
but lots of people that do this all the time tell me it will just work. | 0:21:46 | 0:21:50 | |
So, buoyed by that tried but not tested scientific endorsement, | 0:21:50 | 0:21:54 | |
we assemble the Slingsby Swallow mark II. | 0:21:54 | 0:21:57 | |

Situation update, three days in. | 0:22:15 | 0:22:17 | |
This is mine and Simmy's beautiful fuselage which is the squarest thing | 0:22:17 | 0:22:21 | |
this side of Michael Gove. | 0:22:21 | 0:22:23 | |
Over here the students are working on the starboard wing, | 0:22:23 | 0:22:27 | |
working very hard on that, they've been here since 10.30. | 0:22:27 | 0:22:30 | |
Over here there's more students, they're working on the port wing, | 0:22:30 | 0:22:34 | |
similar level of progress, we've got to add the aileron, a bit of covering and so on, | 0:22:34 | 0:22:38 | |
and then over here all the bits at the tail plane, | 0:22:38 | 0:22:41 | |
the fin and the rudder, tail plane being sanded to final shape. | 0:22:41 | 0:22:45 | |
'Compared with my childhood glider builds, we're making rapid progress | 0:22:45 | 0:22:50 | |
'thanks to modern inventions like superglues. | 0:22:50 | 0:22:53 | |
'They really will stick anything.' | 0:22:53 | 0:22:55 | |
This is something that's happened quite a few times already, | 0:22:56 | 0:22:59 | |
but I stuck my thumb to the aeroplane with a stray blob of the Cyano glue. | 0:22:59 | 0:23:04 | |
You can see the bit that's gone. | 0:23:04 | 0:23:08 | |
It's my flesh. Eugh! | 0:23:08 | 0:23:10 | |
'So, after days in a hangar, anointing the glider with our blood, sweat and ravaged flesh, | 0:23:14 | 0:23:19 | |
'after hundreds of pieces of balsa and more craft work than a German nightclub, | 0:23:19 | 0:23:26 | |
'the new and improved Swallow is finally ready.' | 0:23:26 | 0:23:31 | |
This, I've come to realise, is in fact a very British endeavour. | 0:23:35 | 0:23:38 | |
We come here inappropriately dressed for the conditions. | 0:23:38 | 0:23:42 | |
We are a motley assortment of experts and hobbyists, drinking tea | 0:23:42 | 0:23:46 | |
and working very long hours for no money in an old and leaky shed. | 0:23:46 | 0:23:50 | |
And yet, I believe we have achieved greatness. | 0:23:50 | 0:23:54 | |
And here it is. | 0:23:54 | 0:23:56 | |
DRAMATIC MUSIC | 0:23:56 | 0:24:00 | |
The Slingsby Swallow. | 0:24:10 | 0:24:11 | |
Lightly modified by us and still basically a balsa wood glider, | 0:24:11 | 0:24:15 | |
just like the ones we all made as kids, | 0:24:15 | 0:24:18 | |
only a bit bigger, but it will unite nations. | 0:24:18 | 0:24:21 | |
Finally, a glider fit to carry my childhood vision on its record-breaking flight. | 0:24:23 | 0:24:28 | |
'We sent the joyous news of our achievement | 0:24:30 | 0:24:32 | |
'to our cousins in Calais, but in reply they send us | 0:24:32 | 0:24:36 | |
'not a bottle of champers, but a giant Gallic raspberry.' | 0:24:36 | 0:24:40 | |
The news is this. | 0:24:40 | 0:24:42 | |
Our glider, our simple humble model, | 0:24:42 | 0:24:45 | |
has to be classified as a drone according to British air traffic control, | 0:24:45 | 0:24:49 | |
which is fine, they're very happy with that. | 0:24:49 | 0:24:52 | |
But the French don't really recognise it as a drone. | 0:24:52 | 0:24:56 | |
They don't like the idea of an unmanned aerial vehicle full of gizmos | 0:24:56 | 0:24:59 | |
entering their airspace and we've had a massive argument about it, | 0:24:59 | 0:25:03 | |
but they won't budge, and we've also of course got the restrictions | 0:25:03 | 0:25:06 | |
of the big lockdown because of some running and jumping competition | 0:25:06 | 0:25:10 | |
that's going on in London, and... | 0:25:10 | 0:25:13 | |
it's really annoying me, to be honest. | 0:25:13 | 0:25:15 | |
I mean France, la belle France, it is a wonderful place to go and drive around, | 0:25:15 | 0:25:19 | |
ride around on a motorcycle or a bicycle, | 0:25:19 | 0:25:21 | |
and yes, you get cassoulet by the side of the road. | 0:25:21 | 0:25:24 | |
It's very nice, they have wonderful cheeses, excellent local red wines, | 0:25:24 | 0:25:28 | |
it's a beautiful place, but at a bureaucratic level, | 0:25:28 | 0:25:31 | |
they make us and the Indians look like schoolchildren. | 0:25:31 | 0:25:33 | |
They're absolutely hopeless, but it doesn't matter, because we've got a plan. | 0:25:33 | 0:25:37 | |
We've discovered another channel that's perfect for our attempt. | 0:25:37 | 0:25:41 | |
This one is free of French hubris and Olympic interference, | 0:25:41 | 0:25:45 | |
but presents us with exactly the same | 0:25:45 | 0:25:47 | |
22-mile record-breaking challenge. | 0:25:47 | 0:25:49 | |
What's more, we'll still be extending | 0:25:49 | 0:25:52 | |
our giant balsa hand of friendship to a foreign power. | 0:25:52 | 0:25:55 | |
We're going to fly from Devon across the Bristol Channel to Wales. | 0:25:55 | 0:25:59 | |
We can even make Wales look a bit like France if we want to with some | 0:25:59 | 0:26:03 | |
clever voiceover and some accordion music and a picture of a croissant. | 0:26:03 | 0:26:06 | |
I prefer it actually. This is better. | 0:26:06 | 0:26:10 | |
So, we've swapped Calais for the valleys, | 0:26:11 | 0:26:14 | |
and the British record will still be ours for the taking. | 0:26:14 | 0:26:17 | |
However, we've had to admit that there is a fundamental flaw in our plan, | 0:26:17 | 0:26:22 | |
something more hopelessly optimistic | 0:26:22 | 0:26:24 | |
than building a giant glider in the first place. | 0:26:24 | 0:26:29 | |
We've made the momentous decision that the balloon launch is a stupid idea, | 0:26:29 | 0:26:33 | |
because basically you only need the slightest puff of wind, | 0:26:33 | 0:26:36 | |
the slightest bit of rain, somebody with an air rifle, | 0:26:36 | 0:26:38 | |
and it doesn't work properly and you lose the balloon, it's no good. | 0:26:38 | 0:26:41 | |
We've decided we're going to go with a helicopter very much like this one. | 0:26:41 | 0:26:45 | |
We'll have one helicopter to film the flight for your entertainment, and one like this to launch it, | 0:26:45 | 0:26:50 | |
and it's good, because it can go up when we want it to, | 0:26:50 | 0:26:52 | |
it can go up to where we want it to, it can go up and down quickly if we | 0:26:52 | 0:26:56 | |
have a technical problem or a camera doesn't work or something like that. | 0:26:56 | 0:27:00 | |
There is, however, a problem. | 0:27:00 | 0:27:03 | |
You can't just chuck a glider out of a hovering helicopter. | 0:27:03 | 0:27:07 | |
For a start, it could get tangled up in this bit, | 0:27:07 | 0:27:09 | |
the complicated mechanism up at the top, and that would be a disaster. | 0:27:09 | 0:27:13 | |
Furthermore, the glider itself might be destroyed | 0:27:13 | 0:27:16 | |
by the enormous down draught. | 0:27:16 | 0:27:18 | |
So, at the last minute Simmy comes up with an experimental solution. | 0:27:18 | 0:27:22 | |
Excellent. You join us now at Dunkeswell Airfield where we have introduced this. | 0:27:22 | 0:27:27 | |
We call it the crate, it's a sort of glider coffin upside down, if you like. | 0:27:27 | 0:27:31 | |
Because we're now going under a helicopter | 0:27:31 | 0:27:34 | |
we can't simply hang the glider underneath, | 0:27:34 | 0:27:36 | |
it would start flying as the helicopter moves along. | 0:27:36 | 0:27:39 | |
So it's shrouded in this, which hangs underneath the helicopter, | 0:27:39 | 0:27:42 | |
and then at the appropriate altitude the glider is released, | 0:27:42 | 0:27:45 | |
drops from underneath it and flies away. | 0:27:45 | 0:27:48 | |
Well, Sim, I can see which way round the glider goes. | 0:27:51 | 0:27:53 | |
I'm guessing the wings go in the long bit and the tail goes in the small bit. | 0:27:53 | 0:27:56 | |
-That's it, yes. -How does the release work? | 0:27:56 | 0:27:58 | |
We've got a panel going up to the helicopter, which turns this | 0:27:58 | 0:28:03 | |
electromagnet on, a 24 volt electromagnet. | 0:28:03 | 0:28:05 | |
-Right. -That holds that down, | 0:28:05 | 0:28:08 | |
and then when we're ready, the pilot will release the power to that | 0:28:08 | 0:28:12 | |
and the glider will simply fall out through the opening at the bottom. | 0:28:12 | 0:28:16 | |
But as the glider drops below, | 0:28:16 | 0:28:18 | |
the glider inside the box is effectively in still air. | 0:28:18 | 0:28:22 | |
-Yeah. -As soon as it drops out into this it's going to be in a 15, 20 knot headwind. | 0:28:22 | 0:28:26 | |
Will the glider not just fly up into the helicopter or back into its box? | 0:28:26 | 0:28:29 | |
That's certainly possible. I've never done this before. | 0:28:29 | 0:28:32 | |
-Well, that's why we're testing it, you see. -Yeah. | 0:28:32 | 0:28:35 | |
'As with most of Britain's newest ideas and quite a lot of her military equipment, | 0:28:35 | 0:28:39 | |
'success ultimately depends on gaffer tape.' | 0:28:39 | 0:28:42 | |
-It's fine there. -Sure? -It's fine. | 0:28:42 | 0:28:45 | |
I think if that comes off, it launches. Is it definitely going to stay on? | 0:28:45 | 0:28:50 | |
-Are you sure, Simmy? -We'll see. | 0:28:51 | 0:28:55 | |
Another big concern is whether the crate will start spinning uncontrollably. | 0:28:55 | 0:28:59 | |
If it does, it'll be impossible to stop | 0:28:59 | 0:29:02 | |
and the glider might be destroyed, even if the release system works. | 0:29:02 | 0:29:06 | |
So, to be on the safe side, we nick the airfield's windsock to act as a stabiliser. | 0:29:07 | 0:29:11 | |
This is the first time a glider has been in the crate. | 0:29:17 | 0:29:19 | |
This isn't the final glider, this is the prototype, which you will | 0:29:19 | 0:29:22 | |
remember being test flown off the hill. | 0:29:22 | 0:29:25 | |
We're not going to drop our proper one for the first time, cos that would just be too risky. | 0:29:25 | 0:29:30 | |
The success of this operation now, everything we've done, | 0:29:33 | 0:29:36 | |
the wind tunnel, the design, the new wings, calculating the glide ratio, | 0:29:36 | 0:29:40 | |
building it in the hangar, it all really hinges on Sim's woodwork | 0:29:40 | 0:29:44 | |
and an electromagnet that we had left over from another project. | 0:29:44 | 0:29:48 | |
This actually has to work. | 0:29:50 | 0:29:51 | |
If this doesn't work, I'm not sure what we can do in time for tomorrow. | 0:29:51 | 0:29:55 | |
Here we go. | 0:29:59 | 0:30:00 | |
Hey, the windsock works! | 0:30:17 | 0:30:19 | |
Look at that! That's tremendous! | 0:30:20 | 0:30:23 | |
'Time for the release mechanism. Here we go.' | 0:30:30 | 0:30:33 | |
-SIMMY YELLS -Yes! Look at that! | 0:30:39 | 0:30:44 | |
Genius! | 0:30:44 | 0:30:46 | |
Well done! | 0:30:46 | 0:30:48 | |
That's the best thing I've ever seen! That's just fabulous! | 0:30:55 | 0:30:58 | |
MUSIC: "99 Balloons" by Goldfinger | 0:30:58 | 0:31:03 | |
It's beautiful as well, look at it! | 0:31:10 | 0:31:12 | |
Look at that! | 0:31:16 | 0:31:18 | |
That's magnificent. | 0:31:22 | 0:31:25 | |
It works! | 0:31:27 | 0:31:29 | |
-Don't sound so amazed. -I'm not amazed, I knew it would work, | 0:31:29 | 0:31:32 | |
-but it's just, when you first see it and you think, "yes!" -Yeah. | 0:31:32 | 0:31:35 | |
You've got that ugly, no offence, Sim, that ugly, square box, | 0:31:35 | 0:31:39 | |
and then this beautiful thing drops out of it and flies. | 0:31:39 | 0:31:43 | |
It is Lazarus, isn't it, because that thing is like a tomb | 0:31:43 | 0:31:46 | |
and then the glider lives, it's raised, except it's lowered. | 0:31:46 | 0:31:50 | |
That's a terrible analogy, cut it out. | 0:31:50 | 0:31:52 | |
Absolutely awesome sauce. | 0:31:55 | 0:31:56 | |
This is really just a very, very convoluted | 0:31:56 | 0:31:59 | |
and elaborate woodwork project, but everything about it works. | 0:31:59 | 0:32:03 | |
All we need now is a decent bit of weather, and that's all we need. | 0:32:03 | 0:32:07 | |
And then we'll make model aviation history. | 0:32:07 | 0:32:10 | |
Great. Shall we have a pint and talk about it? | 0:32:10 | 0:32:13 | |
-Definitely. -Let's do that. | 0:32:13 | 0:32:14 | |
'Oh, yes. The weather. | 0:32:16 | 0:32:18 | |
'Just as we're packing up and preparing to go to the pub, the phone rings.' | 0:32:18 | 0:32:22 | |
Oh, somebody's ringing in. Oh, it's him, it's Charlie from the Met Office. | 0:32:22 | 0:32:26 | |
Charlie. Hello. How are you? | 0:32:28 | 0:32:31 | |
Rain? | 0:32:42 | 0:32:44 | |
I'll try you later on, then. | 0:32:45 | 0:32:49 | |
All right. Thanks very much. Cheers. Bye. Bye. | 0:32:49 | 0:32:52 | |
Is that off? Yes. | 0:32:54 | 0:32:55 | |
That's remarkable - there's a man who actually does speak like a weather forecast. | 0:32:55 | 0:32:59 | |
Even though I was just asking him casually, he was saying, | 0:32:59 | 0:33:02 | |
"And in the morning we'll see some bright, sunny patches, | 0:33:02 | 0:33:05 | |
"but with cloud cover increasing towards the middle of the day | 0:33:05 | 0:33:08 | |
"and there may be some light showers from 3..." | 0:33:08 | 0:33:10 | |
Do you think he speaks like that at home? | 0:33:10 | 0:33:12 | |
His wife says, "Would you like a cup of tea, darling?" | 0:33:12 | 0:33:14 | |
"I'm interested in the cup of tea approaching from the kitchen in a westerly direction, | 0:33:14 | 0:33:18 | |
"temperature roughly 80 to 85 degrees C, becoming colder". | 0:33:18 | 0:33:22 | |
It's just remarkable. I thought I'd rung up the telly. | 0:33:22 | 0:33:28 | |
Anyway, the gist of it is tomorrow is good in the morning | 0:33:28 | 0:33:31 | |
but there will be quite a bit of cloud, and the wind is favourable, | 0:33:31 | 0:33:34 | |
and the wind isn't favourable in the afternoon, but with | 0:33:34 | 0:33:37 | |
light showers developing and the cloud base increasing and lowering. | 0:33:37 | 0:33:40 | |
So, tomorrow's pretty bad. Umm... | 0:33:40 | 0:33:42 | |
Which will mean crossing from England to Wales will be difficult. | 0:33:44 | 0:33:47 | |
-Scotland has seen some heavy showers with a risk of snowfall. -LAUGHTER OFF CAMERA | 0:33:51 | 0:33:56 | |
Actually, this isn't funny. | 0:33:56 | 0:33:58 | |
The bad weather forecast, as feared, could ruin everything. | 0:33:58 | 0:34:02 | |
We can only afford one shot at the record. | 0:34:02 | 0:34:05 | |
'Cancelling the helicopters at this late stage | 0:34:05 | 0:34:08 | |
'would be prohibitively expensive. | 0:34:08 | 0:34:10 | |
'The flight will have to go ahead.' | 0:34:10 | 0:34:13 | |
SOARING ORCHESTRAL MUSIC | 0:34:23 | 0:34:30 | |
Good morning. It's Friday, it's launch day. | 0:34:33 | 0:34:36 | |
In a moment this will be hoisted aloft | 0:34:36 | 0:34:38 | |
and dropped from the special crate. | 0:34:38 | 0:34:40 | |
I will be jumping into a very fast boat, which is why I'm dressed like this, | 0:34:40 | 0:34:44 | |
to pursue it across the Bristol Channel, | 0:34:44 | 0:34:46 | |
and the weather is not perfect, to be honest, | 0:34:46 | 0:34:48 | |
but these helicopters and all these people cost a lot of money | 0:34:48 | 0:34:52 | |
and we have no choice but to go for it. On the plus side, the glider is, | 0:34:52 | 0:34:56 | |
and the production crew think this is extremely funny, piloted by me. | 0:34:56 | 0:35:01 | |
So what could...? What terrible thing could befall it? | 0:35:01 | 0:35:05 | |
It's difficult to imagine. Look. Look, it's me. | 0:35:05 | 0:35:09 | |
'Moments before the launch, I convene the crew to go over the perfectly simple plan.' | 0:35:10 | 0:35:15 | |
Dover is now Devon and France is now Wales. | 0:35:15 | 0:35:18 | |
The balloon is now a helicopter | 0:35:18 | 0:35:19 | |
and we launch from Simmy's glider coffin at a height | 0:35:19 | 0:35:22 | |
of at least 8,000 feet if we want to set the 22-mile record. | 0:35:22 | 0:35:25 | |
I'll follow in a speedboat so I can recover the glider | 0:35:25 | 0:35:28 | |
when it hits the deck, and there'll also be a second helicopter | 0:35:28 | 0:35:30 | |
with a glider spotter to keep an eye on it. Simple! | 0:35:30 | 0:35:33 | |
'Despite the early hour, I'm experiencing that same | 0:35:36 | 0:35:39 | |
'frisson of excitement I felt as a ten-year-old. | 0:35:39 | 0:35:42 | |
'Our glider is finally going to take wing.' | 0:35:42 | 0:35:45 | |
Right, here we go, and we're heading for Wales, | 0:35:45 | 0:35:48 | |
but that obviously is a bit academic. | 0:35:48 | 0:35:50 | |
It's a free flight glider. | 0:35:50 | 0:35:52 | |
The whole point is you let it go and you see what happens. | 0:35:52 | 0:35:56 | |
And when the Swallow drops out of that ugly crate, | 0:35:56 | 0:35:59 | |
it will be transformed from a scientific experiment into a magical thing, | 0:35:59 | 0:36:04 | |
and it isn't magic, really, it's physics, it's about aerofoils | 0:36:04 | 0:36:08 | |
and weights and balance and air flow and all the other things we've talked about. | 0:36:08 | 0:36:12 | |
But actually, it IS magic. To the boat! | 0:36:12 | 0:36:17 | |
MUSIC: "When The Levee Breaks" by Led Zeppelin | 0:36:17 | 0:36:21 | |
'This is it. The clouds are threatening, the plan is convoluted, but the team is ready.' | 0:36:21 | 0:36:26 | |
Is it working? | 0:36:29 | 0:36:31 | |
It's working. | 0:36:31 | 0:36:34 | |
Go. | 0:36:34 | 0:36:35 | |
'We appear to have reverted to impatient ten-year-olds, | 0:36:36 | 0:36:40 | |
'but in reality we are a crack team. Every second counts.' | 0:36:40 | 0:36:44 | |
VOICE FROM WALKIE-TALKIE | 0:36:44 | 0:36:47 | |
Unlock the van. | 0:36:47 | 0:36:48 | |
'Sadly, Fatty Carswell, our Australian cameraman, | 0:36:50 | 0:36:53 | |
'has confused his van keys with a fun-sized Mars bar, costing us vital seconds. | 0:36:53 | 0:36:57 | |
'As the glider helicopter flies on oblivious, | 0:37:02 | 0:37:05 | |
'we drive frantically to the harbour and our waiting speedboat.' | 0:37:05 | 0:37:08 | |
There's no boat. | 0:37:10 | 0:37:13 | |
'I don't believe this.' | 0:37:13 | 0:37:15 | |
Yeah, there's absolutely nobody here. | 0:37:15 | 0:37:18 | |
'Boarding the glider recovery speedboat was meant to be | 0:37:18 | 0:37:20 | |
'like something from the opening sequence of a Bond film. | 0:37:20 | 0:37:23 | |
'Meanwhile, our helicopter is already starting its ascent to launch height.' | 0:37:25 | 0:37:30 | |
-There's no -BLEEP -boat here. | 0:37:31 | 0:37:33 | |
'With chaos fast overtaking us, it's up to the director to keep a level head.' | 0:37:33 | 0:37:37 | |
The slip road to the harbour? | 0:37:37 | 0:37:39 | |
-BLEEP -it's at the wrong -BLEEP -place, it should be at the -BLEEP BLEEP. | 0:37:39 | 0:37:43 | |
'Meanwhile, in the chopper, our glider spotter, | 0:37:43 | 0:37:46 | |
-'Tom, is having his own doubts.' -James, this is Tom. | 0:37:46 | 0:37:48 | |
Roger, go ahead, Tom. | 0:37:48 | 0:37:51 | |
We are currently at 4,000 feet above the coastline, slightly | 0:37:51 | 0:37:55 | |
concerned about the amount of cloud out here in the Bristol Channel. | 0:37:55 | 0:37:59 | |
At the moment we can't see Oxwich. | 0:37:59 | 0:38:02 | |
Roger, can you stand by? We have a slight boat problem. | 0:38:02 | 0:38:04 | |
As soon as we're in it, we'll make a decision. | 0:38:04 | 0:38:06 | |
'The cloud cover is fast becoming an even bigger issue than the boat. | 0:38:07 | 0:38:11 | |
'Neither of our helicopters is permitted to fly in cloud. | 0:38:11 | 0:38:15 | |
'Our pilots have to be able to see the ground at all times. | 0:38:15 | 0:38:18 | |
'On top of that, two helicopters flying blind next to each other | 0:38:18 | 0:38:21 | |
'could end in what pilots call "the drink", | 0:38:21 | 0:38:25 | |
'especially when one of them is swinging a two-tonne woodwork project on a rope. | 0:38:25 | 0:38:29 | |
'But look on the bright side. Our speedboat has now turned up, | 0:38:29 | 0:38:32 | |
'meaning we will at least be able to recover the chopper crews.' | 0:38:32 | 0:38:35 | |
Golf, Oscar, Alpha, this is James, | 0:38:39 | 0:38:42 | |
just to confirm you are west of Ilfracombe, is that correct? | 0:38:42 | 0:38:45 | |
-'That's correct.' -Roger. We're almost ready for you to launch. | 0:38:45 | 0:38:48 | |
Give us a minute or two to position. | 0:38:48 | 0:38:50 | |
Currently if we launched from this location | 0:38:52 | 0:38:55 | |
we would be almost directly into cloud. | 0:38:55 | 0:38:58 | |
I can't see them. Can anybody see them? | 0:38:58 | 0:39:00 | |
The delay with our boat has meant the weather has closed in. | 0:39:01 | 0:39:05 | |
The helicopter's rotors are now beating the base of the clouds. | 0:39:05 | 0:39:08 | |
Tom, our glider spotter, has an emergency remote control | 0:39:10 | 0:39:13 | |
to abort the flight if it's about to crash into an orphanage, | 0:39:13 | 0:39:16 | |
but flight regulations say we can't launch if he can't see. | 0:39:16 | 0:39:21 | |
They will launch the glider, might go into cloud, | 0:39:21 | 0:39:23 | |
in which case it'll have to abort. | 0:39:23 | 0:39:25 | |
It's an impossible situation. | 0:39:27 | 0:39:29 | |
We can't fly higher, we can't launch into cloud, | 0:39:29 | 0:39:32 | |
and we can't wait any longer. | 0:39:32 | 0:39:34 | |
Right, Tom, is there a case for launching slightly lower | 0:39:35 | 0:39:38 | |
so that we miss the cloud? | 0:39:38 | 0:39:40 | |
Yes, I would say so, if we were in 500 feet of the cloud base. | 0:39:40 | 0:39:44 | |
OK, do the descent by 500 feet and then we'll go for distance. | 0:39:45 | 0:39:49 | |
Roger. | 0:39:49 | 0:39:51 | |
Reducing altitude by 500 feet so that we clear the cloud. | 0:39:51 | 0:39:54 | |
The helicopter is forced to descend to 2,900 feet, massively lower | 0:39:56 | 0:40:00 | |
than the 8,000 we were hoping for, to search for a break in the clouds. | 0:40:00 | 0:40:05 | |
James, we are now visual with the boat, say again, visual with your boat. | 0:40:07 | 0:40:11 | |
Right, there's the film chopper, there's the launch chopper. | 0:40:11 | 0:40:15 | |
Right, this is James in the boat. | 0:40:15 | 0:40:16 | |
Golf, Oscar, Alpha, Golf, X-ray, X-ray, | 0:40:16 | 0:40:19 | |
please launch at will at your discretion, and report when done. | 0:40:19 | 0:40:23 | |
Four, three, two, one, | 0:40:29 | 0:40:32 | |
go. | 0:40:32 | 0:40:34 | |
We can see that, thank you very much, that's gorgeous. Fabulous. | 0:40:45 | 0:40:48 | |
Look at that! | 0:40:48 | 0:40:51 | |
James, autopilot is engaged. | 0:40:51 | 0:40:53 | |
Roger, autopilot engaged. | 0:40:54 | 0:40:57 | |
Cloud base not your fault, Oscar Alpha, thank you. | 0:40:57 | 0:40:59 | |
Yeah, all right, Tom. Anyway, our glider is finally in the air, | 0:41:05 | 0:41:09 | |
but the observant among you will have noticed something wrong. | 0:41:09 | 0:41:13 | |
Shouldn't it be heading out to sea? | 0:41:13 | 0:41:16 | |
James, we're getting a lot of pitching fluctuation at the moment. | 0:41:16 | 0:41:19 | |
Actually, I can see that from down here. | 0:41:19 | 0:41:22 | |
James to Tom, it's quite difficult to see from here. | 0:41:25 | 0:41:28 | |
Which way is it actually heading? | 0:41:28 | 0:41:29 | |
Heading east along the coastline. | 0:41:29 | 0:41:32 | |
Well, that's not right. | 0:41:32 | 0:41:34 | |
We're not sure if it's an autopilot malfunction or just a fear of the Welsh, | 0:41:34 | 0:41:38 | |
but either way, the Swallow appears to be heading back to base. | 0:41:38 | 0:41:42 | |
But then... | 0:41:48 | 0:41:50 | |
-It's going the right way now. -Yeah. | 0:42:00 | 0:42:03 | |
OK? Chase it skipper. | 0:42:13 | 0:42:16 | |
Good. We've got to pick up speed. | 0:42:16 | 0:42:17 | |
'The glider is now at altitude 1,000 and still tracking towards Oxwich Bay.' | 0:42:36 | 0:42:43 | |
Roger, 1,000 Oxwich Bay. It looks lovely from down here, how does it look from up there? | 0:42:43 | 0:42:47 | |
'The view is absolutely gorgeous.' | 0:42:47 | 0:42:49 | |
Look at it. | 0:42:52 | 0:42:54 | |
Beautiful. | 0:42:54 | 0:42:55 | |
It really is a spectacular sight, | 0:43:09 | 0:43:12 | |
but nothing can disguise the fact that what with the weather, | 0:43:12 | 0:43:15 | |
the boat, the autopilot and the Mars bar, we were just too low. | 0:43:15 | 0:43:20 | |
'Glider's in the water. James, run it down.' | 0:43:34 | 0:43:37 | |
Roger, we have visual. Thanks. | 0:43:37 | 0:43:39 | |
-How far from shore are we? -Two and a half miles. | 0:43:42 | 0:43:45 | |
Two and a half miles, that's hopeless. | 0:43:45 | 0:43:47 | |
I think it's struggling. | 0:43:58 | 0:44:00 | |
Top work. Beautiful. | 0:44:05 | 0:44:08 | |
'Two and a half miles, nearly 20 miles short of the record, | 0:44:11 | 0:44:16 | |
'and still in sight of Devon. | 0:44:16 | 0:44:18 | |

MUSIC: "Baba O'Riley" by The Who | 0:45:01 | 0:45:05 | |
I know I said yesterday that that would be our only chance, | 0:45:09 | 0:45:12 | |
and strictly speaking it was. | 0:45:12 | 0:45:14 | |
All these people, helicopter pilots, Simmy, the boat man, | 0:45:14 | 0:45:17 | |
they're now all on very expensive overtime, but look at the weather. | 0:45:17 | 0:45:20 | |
Look at the sky, it's clear. | 0:45:20 | 0:45:21 | |
The helicopter can go as high as it likes. | 0:45:21 | 0:45:24 | |
The problem is, though, you will remember | 0:45:24 | 0:45:26 | |
we were going to extend the hand of friendship to Wales, | 0:45:26 | 0:45:29 | |
we were going to go from North Devon over to the bay here at Oxwich. | 0:45:29 | 0:45:33 | |
The problem is the wind today is a dead easterly. | 0:45:33 | 0:45:37 | |
It's going that way, which makes it virtually impossible, | 0:45:37 | 0:45:40 | |
but then we discovered the Isle of Lundy down here, | 0:45:40 | 0:45:44 | |
directly to the west of our launch point, | 0:45:44 | 0:45:47 | |
and more to the point, that is a distance of 22 nautical miles, | 0:45:47 | 0:45:51 | |
almost exactly the same as the Channel. | 0:45:51 | 0:45:54 | |
That's where we'll fly to, and I know it's not Wales, | 0:45:54 | 0:45:57 | |
and that's a bit disappointing, but we thought for the purposes of this film, | 0:45:57 | 0:46:01 | |
we'll spell Lundy with two Ls and we'll call it Llundy. | 0:46:01 | 0:46:05 | |

# Let's get together before we get much older. # | 0:46:39 | 0:46:45 | |
We're going to go halfway between Ilfracombe and Lundy, | 0:46:45 | 0:46:48 | |
wait for news of the glider's launch, | 0:46:48 | 0:46:50 | |
which we won't be able to see because it's going to be at at least 8,500 feet, | 0:46:50 | 0:46:53 | |
and then, following directions from our satellite navigation tracker, | 0:46:53 | 0:46:57 | |
who's sitting on a hilltop, we'll learn how fast it's going, | 0:46:57 | 0:47:00 | |
which direction it's going in towards Lundy, hopefully, | 0:47:00 | 0:47:03 | |
and chase it and hopefully meet it as it comes in to an elegant landing. | 0:47:03 | 0:47:07 | |
While we head out to sea, the helicopters describe huge ascending spirals over Ilfracombe | 0:47:07 | 0:47:13 | |
as they climb to launch altitude. | 0:47:13 | 0:47:15 | |
'We're just coming up to 5,000 feet.' | 0:47:24 | 0:47:27 | |
'OK, 6,000 feet now.' | 0:47:30 | 0:47:32 | |
Roger, 6,000 feet. Sounds excellent. | 0:47:33 | 0:47:36 | |
So, we're already more than twice as high as we were yesterday. | 0:47:39 | 0:47:42 | |
'OK, so it's six to 7,000 now.' | 0:47:43 | 0:47:45 | |
Roger, 7,000, can you keep going? | 0:47:48 | 0:47:50 | |
-'Yeah, we can, definitely' -It's tremendous. | 0:47:50 | 0:47:53 | |
We're now just shy of our 8,000 foot launch height, but the weather is | 0:47:55 | 0:48:00 | |
so good, the choppers can go higher than we ever thought possible. | 0:48:00 | 0:48:04 | |
'9,000 feet now.' | 0:48:04 | 0:48:06 | |
9,000 feet. | 0:48:07 | 0:48:09 | |
MUSIC: "I Can See For Miles" by The Who | 0:48:09 | 0:48:14 | |
-'Altitude 9,500.' -Oh! | 0:48:14 | 0:48:16 | |
'And half a mile in your 8 o'clock clearing.' | 0:48:16 | 0:48:18 | |
# I can see for miles and miles | 0:48:18 | 0:48:22 | |
# And miles and miles and miles. # | 0:48:22 | 0:48:30 | |
'Altitude 10,000.' | 0:48:31 | 0:48:33 | |
At a final altitude of 10,000 feet plus a length of rope, we're ready. | 0:48:34 | 0:48:39 | |
The island is behind us and at sea level the wind is | 0:48:42 | 0:48:45 | |
directly in my face, as I look east, so it's going to be | 0:48:45 | 0:48:49 | |
behind the glider and it's going to go belting along. | 0:48:49 | 0:48:53 | |
It's probably going to have an air speed of something like 35 knots. | 0:48:53 | 0:48:56 | |
'OK, we're ready.' | 0:48:56 | 0:48:59 | |
'Ten, nine, eight, seven, six, five, four, | 0:48:59 | 0:49:05 | |
'three, two one. Release.' | 0:49:05 | 0:49:09 | |
'That's glider gone.' | 0:49:20 | 0:49:22 | |
Yes! | 0:49:22 | 0:49:23 | |
'It's fantastic!' | 0:49:23 | 0:49:25 | |
Golf, X-ray, X-ray, this is the boat. | 0:50:05 | 0:50:07 | |
Can you give us an approximation of the glider ground speed please? | 0:50:07 | 0:50:11 | |
'OK, James, it looks like we're making 30 knots ground speed.' | 0:50:13 | 0:50:18 | |
Hey! Roger, 30 knots, thank you. | 0:50:18 | 0:50:20 | |
-'James, this is Tom.' -Tom, fire away. | 0:50:27 | 0:50:29 | |
'The glider seems to be tracking well towards Lundy.' | 0:50:29 | 0:50:32 | |
We're already a mile offshore with the glider and we've only lost | 0:50:36 | 0:50:39 | |
-about 1,000, well less than 1,000, feet, so yeah, we need to crack on. -Yeah. | 0:50:39 | 0:50:44 | |
'This is the fastest boat in Ilfracombe, | 0:50:44 | 0:50:47 | |
'but it isn't fast enough. I do a quick calculation. | 0:50:47 | 0:50:50 | |
'Even though we can't see the glider yet, | 0:50:50 | 0:50:52 | |
'I know we're never going to beat it to Lundy. | 0:50:52 | 0:50:55 | |
'It's just flying too well for that.' | 0:50:55 | 0:50:58 | |
It's remaining relatively stable. | 0:50:58 | 0:51:00 | |
OK, and do we think, I know you don't know it exactly, | 0:51:00 | 0:51:03 | |
but is it at best distance glide speed? | 0:51:03 | 0:51:06 | |
I would say it's looking very promising at the moment. | 0:51:06 | 0:51:09 | |
'Altitude 8,900.' | 0:51:14 | 0:51:16 | |
So, we've done a mile and a bit and we've only lost 1,000 feet, | 0:51:18 | 0:51:21 | |
so it's gone nearly two miles, well it'll just make it at this rate. | 0:51:21 | 0:51:25 | |
Yeah, but it may not clear the cliffs, | 0:51:25 | 0:51:27 | |
but if it lands on the beach, I count that as a success. | 0:51:27 | 0:51:30 | |
It's going a mile per 1,000 feet now. | 0:51:30 | 0:51:32 | |
Sorry, two miles per 1,000 feet. | 0:51:32 | 0:51:34 | |
Being told how well the swallow is flying is very gratifying, | 0:51:35 | 0:51:38 | |
but no match for seeing it with our own eyes. | 0:51:38 | 0:51:42 | |
But then... | 0:51:42 | 0:51:44 | |
We've made visual. We can see you. Fantastic! | 0:51:49 | 0:51:52 | |
Hello, X-ray, X-ray, you're dead above us. | 0:51:52 | 0:51:55 | |
Isn't that cool? | 0:51:55 | 0:51:56 | |
'As I said, you spend hours on it, but it's all worth it.' | 0:51:58 | 0:52:03 | |
That's miles up! | 0:52:03 | 0:52:06 | |
'Upper air turbulence is giving the autopilot a hard time, | 0:52:06 | 0:52:09 | |
'but no matter. | 0:52:09 | 0:52:10 | |
'Wood, glue and a few bits of finger have rewarded us | 0:52:10 | 0:52:14 | |
'with the gift of flight.' | 0:52:14 | 0:52:15 | |
'James, this is Tom.' | 0:53:01 | 0:53:03 | |
'Hello, Tom, go ahead.' | 0:53:05 | 0:53:07 | |
Glider is flying fantastically. | 0:53:07 | 0:53:09 | |
'Altitude, 4,500 feet.' | 0:53:09 | 0:53:13 | |
We should cross the island at this rate at just under 2,000 feet, which would be absolutely fantastic. | 0:53:13 | 0:53:18 | |
We can land it where we like. We can fly it through the lighthouse keeper's kitchen window. | 0:53:18 | 0:53:22 | |
Continue, Sir. | 0:53:22 | 0:53:23 | |
Llundy hoy! | 0:53:32 | 0:53:34 | |
WELSH MALE VOICE CHOIR SINGS | 0:53:34 | 0:53:38 | |
'We have to dock our speedboat at a jetty round the side of Lundy. | 0:54:14 | 0:54:18 | |
'For the first time since midway, we're forced to lose sight of our toy. | 0:54:18 | 0:54:22 | |
'Although, to be fair, the goodwill will be dampened | 0:54:22 | 0:54:25 | |
'if we drop all the camera kit in the sea.' | 0:54:25 | 0:54:28 | |
Ah, what a shame we can't actually see it, look it's... | 0:54:28 | 0:54:30 | |
I CAN see it! | 0:54:32 | 0:54:34 | |
Ah, it's just gone behind the headland. | 0:54:34 | 0:54:36 | |
I just saw it, see there's the chopper, | 0:54:36 | 0:54:39 | |
I just saw it, we'll see it emerge in a minute, I think. | 0:54:39 | 0:54:42 | |
There it is. Can you see it? | 0:54:42 | 0:54:44 | |
The Swallow soars over Lundy at an amazing 2,300 feet above sea level. | 0:54:52 | 0:54:58 | |
It's still flying fantastically. | 0:55:06 | 0:55:08 | |
'The GPS on the Swallow has been programmed for the landing strip | 0:55:13 | 0:55:16 | |
'on the south side of the island. | 0:55:16 | 0:55:19 | |
'Until then, technically it will be circling that point | 0:55:19 | 0:55:22 | |
'until it loses all its height. | 0:55:22 | 0:55:24 | |
'But from the ground, our toy glider is doing victory laps.' | 0:55:25 | 0:55:30 | |
It's one of those things in childhood when you think, | 0:55:49 | 0:55:51 | |
"If only I could have my bicycle at the top of a really long hill | 0:55:51 | 0:55:54 | |
"so I could enjoy riding downhill all day," and it's the same with a glider. | 0:55:54 | 0:55:58 | |
You always think, "If only I could throw it out of something thousands of feet high | 0:55:58 | 0:56:02 | |
"rather than just the bedroom window." That's what we've done. | 0:56:02 | 0:56:05 | |
And that's what it will do. | 0:56:05 | 0:56:07 | |
Fantastic. | 0:56:09 | 0:56:12 | |
I know it's only a toy glider, but allow me to be a bit emotional about it. | 0:56:12 | 0:56:15 | |
After nearly an hour of heroic gliding, | 0:56:18 | 0:56:21 | |
it's time for the migrating Swallow to land. | 0:56:21 | 0:56:23 | |
Come on, come on. | 0:56:27 | 0:56:29 | |
-HE LAUGHS -James this is Tom. The glider has landed on Lundy. | 0:56:50 | 0:56:53 | |
How many feet would you say that is off the runway? | 0:56:53 | 0:56:56 | |
-20 feet. -Approximately 20 feet off the runway. | 0:56:56 | 0:57:00 | |
22 nautical mile, that's just brilliant. | 0:57:00 | 0:57:03 | |
From almost beyond the horizon, from the other world, we are pioneers, | 0:57:04 | 0:57:10 | |
we are discoverers setting foot on this strange place with no cars in it. | 0:57:10 | 0:57:14 | |
And so I head across the island to bring our glider home. | 0:57:16 | 0:57:20 | |
But, like Captain Cook's landing party, | 0:57:20 | 0:57:23 | |
first the Swallow must survive an encounter with the natives. | 0:57:23 | 0:57:26 | |
It's a play one. | 0:57:27 | 0:57:29 | |
It says it's from James. | 0:57:32 | 0:57:35 | |
Oh, look, there's a little man in the front. Somebody's made it, haven't they? | 0:57:35 | 0:57:39 | |
I know which guy that is off Top Gear. He's the really stupid one. | 0:57:39 | 0:57:43 | |
'Luckily for them, it takes the stupid one | 0:57:43 | 0:57:46 | |
'so long to hike across the island that the locals have run away.' | 0:57:46 | 0:57:49 | |
Bye, if I'm on TV! | 0:57:49 | 0:57:51 | |
-Well done. -Thank you very much. -Thank you. | 0:57:52 | 0:57:54 | |
If you look behind you very briefly you will see where our glider has come from, | 0:58:04 | 0:58:09 | |
Ilfracombe sticking out over there, | 0:58:09 | 0:58:12 | |
only just visible in the slight haze. | 0:58:12 | 0:58:14 | |
This has been a pioneering flight by a toy glider, one that's never been made before, | 0:58:14 | 0:58:18 | |
and it set off like the Mayflower or Apollo VIII, | 0:58:18 | 0:58:22 | |
not really knowing if this was possible, but here it is, | 0:58:22 | 0:58:27 | |
the first, and remember the first to do something stays in the record book for ever. | 0:58:27 | 0:58:31 | |
In my lifetime, there have been two very important announcements made | 0:58:33 | 0:58:37 | |
concerning historic moments in aviation. | 0:58:37 | 0:58:40 | |
"The eagle has landed", and "The Swallow has flown". | 0:58:40 | 0:58:45 | |
Happy Christmas, and I hope all your toys work as well as ours did. | 0:58:45 | 0:58:49 | |
