0:00:06 > 0:00:08Coming up on Hero Squad -
0:00:10 > 0:00:11six wannabe heroes...
0:00:16 > 0:00:19..facing the worst nature can throw at them.
0:00:21 > 0:00:24There's a new emergency crew in town.
0:00:27 > 0:00:30I'm Rav Wilding, and this is Hero Squad!
0:00:33 > 0:00:37Six ordinary school kids.
0:00:37 > 0:00:40Their mission - to learn how to save lives.
0:00:44 > 0:00:48But do they have what it takes to become real-life heroes?
0:00:53 > 0:00:55In the last instalment of Hero Squad,
0:00:55 > 0:01:00our six cadets are joining the illustrious ranks of the RAF
0:01:00 > 0:01:03and one of Britain's busiest mountain rescue teams.
0:01:04 > 0:01:08In their first rescue with two different emergency services,
0:01:08 > 0:01:10they must use all the skills they've learnt
0:01:10 > 0:01:12so far on their incredible journey.
0:01:14 > 0:01:17Only then will they have earned the right to call themselves heroes.
0:01:18 > 0:01:23As they fly at 120mph into the heart of an emergency storm,
0:01:23 > 0:01:26there'll be technology, thrills, spills,
0:01:26 > 0:01:29and two cadets will become the first ever
0:01:29 > 0:01:32Hero Squad helicopter crew members.
0:01:32 > 0:01:35The wheels are spinning, the rotors are turning,
0:01:35 > 0:01:36someone is in trouble.
0:01:36 > 0:01:39It's time for liftoff, cadets - let's go, go, go!
0:01:41 > 0:01:44We've had adventure, adrenaline and excitement,
0:01:44 > 0:01:46and we're not taking our foot off the gas
0:01:46 > 0:01:48until we cross that finish line.
0:01:48 > 0:01:51The cadets are here in Snowdonia in North Wales,
0:01:51 > 0:01:53and they're about to face a challenge
0:01:53 > 0:01:55that's going to push them right to the limit.
0:01:55 > 0:02:00And I'm about to spring a very big surprise on them. Follow me.
0:02:04 > 0:02:08'I'm joined by Chris Lloyd of Ogwen Valley Mountain Rescue.'
0:02:08 > 0:02:11Morning. How is everyone today?
0:02:11 > 0:02:14'Chris will be mentor for some of the cadets,
0:02:14 > 0:02:16'but the big surprise I'm about to spring is that
0:02:16 > 0:02:20'two Hero Squad members are leaving on a secret assignment.'
0:02:22 > 0:02:25So the two people that are going away right here, right now
0:02:25 > 0:02:29for that special mission...
0:02:29 > 0:02:31is Katy and Kiera.
0:02:31 > 0:02:33Well done, you two.
0:02:33 > 0:02:35It's time to go. Follow me.
0:02:40 > 0:02:43My heart is racing at a thousand miles per hour.
0:02:43 > 0:02:47It's a bit different being split up, but we're all good friends
0:02:47 > 0:02:49so it doesn't matter who we're with.
0:02:52 > 0:02:56I feel really left out now. I'm the only girl left!
0:02:56 > 0:02:58I have no idea what we're going to do,
0:02:58 > 0:03:01or where we're going, cos we're in the middle of nowhere.
0:03:01 > 0:03:05And when he said "secret mission", it's playing on my mind so much.
0:03:05 > 0:03:07It sounds like Mission Impossible, so it's quite...
0:03:07 > 0:03:10I'm going with Katy and Kiera,
0:03:10 > 0:03:13as they set off on their secret mission.
0:03:13 > 0:03:16But for the other cadets, their mission will be with
0:03:16 > 0:03:21the Ogwen Valley Mountain Rescue team, and their mentor, Chris Lloyd.
0:03:21 > 0:03:25Chris has been involved in countless search and rescue missions,
0:03:25 > 0:03:28saving lives and keeping people in the mountains safe.
0:03:32 > 0:03:35First up, the Hero Squad must find a lost walker.
0:03:37 > 0:03:40To do that, they're using a piece of technology
0:03:40 > 0:03:43called the Search And Rescue Locator,
0:03:43 > 0:03:45or SARLOC.
0:03:45 > 0:03:47SARLOC was invented by this member
0:03:47 > 0:03:50of the Ogwen Valley Mountain Rescue, Russell Hore.
0:03:50 > 0:03:53We're currently parked here...
0:03:53 > 0:03:56Andy has taken charge of the control vehicle
0:03:56 > 0:03:58and the SARLOC navigation system.
0:03:58 > 0:04:03Luci, this is Andy from control. Can you please start heading a bit west?
0:04:03 > 0:04:06'Yes, all received, out.'
0:04:06 > 0:04:08This cadet has shown his skill with technology,
0:04:08 > 0:04:11tools and gadgetry all the way through Hero Squad.
0:04:13 > 0:04:15Using radio comms at sea,
0:04:15 > 0:04:19sophisticated navigation techniques in the mountains,
0:04:19 > 0:04:23and mastering hi-tech cutting tools,
0:04:23 > 0:04:25he's used both his brains and his brawn.
0:04:27 > 0:04:30Luci, this is Andy from control.
0:04:30 > 0:04:33SARLOC uses the signal from a mobile to locate lost people,
0:04:33 > 0:04:36and reveal their position on a map.
0:04:36 > 0:04:39The estimated distance is about 100 metres.
0:04:39 > 0:04:42And via radio, Andy guides the cadets
0:04:42 > 0:04:45to the lost walker's location.
0:04:45 > 0:04:47You should be able to see the casualty. Over.
0:04:47 > 0:04:49We have found the missing man,
0:04:49 > 0:04:51and we're just heading over to him now, over.
0:04:51 > 0:04:53- Is your name Andy?- Yeah.
0:04:53 > 0:04:54Job done.
0:05:02 > 0:05:0640 miles away on the island of Anglesey, I can now reveal
0:05:06 > 0:05:09the location for Katy and Kiera's secret assignment.
0:05:11 > 0:05:12They're at RAF Valley.
0:05:15 > 0:05:18Their most famous crew member is none other than Prince William,
0:05:18 > 0:05:21the Duke of Cambridge.
0:05:21 > 0:05:24Known here as Flight Lieutenant Wales, he has served as
0:05:24 > 0:05:26part of this squadron since 2010.
0:05:28 > 0:05:30Katy and Kiera will be under the watchful eye
0:05:30 > 0:05:33of their mentor, and Prince William's senior officer.
0:05:35 > 0:05:37My name is Squadron Leader Alex Brassington,
0:05:37 > 0:05:38and we're going to train you up
0:05:38 > 0:05:40on how to conduct search and rescue operations
0:05:40 > 0:05:43in one of the RAF's Sea King helicopters.
0:05:43 > 0:05:47- How does that sound? - I'm so excited! This is a dream.
0:05:47 > 0:05:50I'm going to wake up in a minute.
0:05:50 > 0:05:52Off you go. Enjoy. Good luck.
0:05:52 > 0:05:54- Looking forward to it?- Yeah.
0:05:55 > 0:05:59Something tells me they're quite excited about this special mission!
0:06:01 > 0:06:05Katy and Kiera are wearing real RAF flying suits,
0:06:05 > 0:06:07and helmets specifically designed for helicopter crews.
0:06:07 > 0:06:10- Speak into there.- Hello!
0:06:10 > 0:06:12The final piece of clothing
0:06:12 > 0:06:15is a flying jacket - and they're good to go.
0:06:15 > 0:06:17It's like a privilege to wear it.
0:06:17 > 0:06:19It feels amazing wearing it all.
0:06:19 > 0:06:22It makes you feel really proud, it's such an honour. Amazing, yeah.
0:06:22 > 0:06:26But there's one more standard issue bit of equipment for the cadets.
0:06:28 > 0:06:30They're sick bags.
0:06:30 > 0:06:32Me and Katy were both the ones
0:06:32 > 0:06:34who actually threw up in the boat last time!
0:06:35 > 0:06:37Training with the RNLI,
0:06:37 > 0:06:42Katy and Kiera both suffered with the motion of the ocean.
0:06:42 > 0:06:43Hopefully we won't need them.
0:06:44 > 0:06:46Once they're kitted up,
0:06:46 > 0:06:49Katy and Kiera get to take a look around the helicopter
0:06:49 > 0:06:51they'll be using in tomorrow's rescue.
0:06:53 > 0:06:56Tomorrow, Katy will be the winch operator.
0:06:56 > 0:07:00She is in charge of the camera and radar systems on the helicopter,
0:07:00 > 0:07:03and also operates the winch at the rescue scene.
0:07:03 > 0:07:05Kiera will be the winchperson,
0:07:05 > 0:07:08who is first on the ground with the casualty.
0:07:09 > 0:07:13So on the port side, you've got the thermal imaging camera...
0:07:13 > 0:07:14As they train,
0:07:14 > 0:07:18Squadron Leader Brassington will be keeping a close eye on them.
0:07:19 > 0:07:22They've never even been on board a helicopter before,
0:07:22 > 0:07:26never mind flown as RAF crew members. Look at those smiles!
0:07:26 > 0:07:32Wait until the other four see this. They're going to be so jealous.
0:07:32 > 0:07:36It feels amazing to be sitting inside a helicopter.
0:07:36 > 0:07:40It's just completely, like, mind-blowing.
0:07:41 > 0:07:44Winch operator Katy is first to be trained,
0:07:44 > 0:07:46as Livvy shows her how to operate
0:07:46 > 0:07:48the Sea King's thermal imaging camera.
0:07:48 > 0:07:52On the left-hand screen we've got the thermal imager,
0:07:52 > 0:07:55the camera that we've just been looking at outside,
0:07:55 > 0:07:58and on my right-hand screen I've also got the radar.
0:07:59 > 0:08:02The camera picks up the heat from a human body,
0:08:02 > 0:08:07and helps the crew locate casualties in remote areas.
0:08:07 > 0:08:08Your direction...
0:08:08 > 0:08:12I'll just show you a little bit of zooming, and then just focus up.
0:08:12 > 0:08:15So we've got quite a range of detail on everything as well.
0:08:15 > 0:08:18It will be Katy's job to use the camera
0:08:18 > 0:08:20to find any possible casualty,
0:08:20 > 0:08:23and guide the pilot towards them.
0:08:23 > 0:08:27Katy was up first for training here, and that's nothing new.
0:08:28 > 0:08:31She's one of the smallest cadets on Hero Squad,
0:08:31 > 0:08:32but she's got to be the bravest.
0:08:34 > 0:08:37On rescues both overground and underground,
0:08:37 > 0:08:41Katy's shown her fearlessness and unbreakable courage.
0:08:43 > 0:08:45I arrive back in Snowdonia
0:08:45 > 0:08:47just in time for the cadets to practise
0:08:47 > 0:08:49putting me into a stretcher.
0:08:51 > 0:08:52Follow me.
0:08:52 > 0:08:55And once the cadets have found what would be a good landing zone
0:08:55 > 0:09:00for a helicopter, it's the end of their last training exercise.
0:09:00 > 0:09:02And lower.
0:09:02 > 0:09:04OK, cadets. Thank you for that.
0:09:08 > 0:09:09Back at RAF Valley,
0:09:09 > 0:09:13Katy and Kiera are facing their final training exercise too.
0:09:13 > 0:09:16They're learning how to use the winch.
0:09:16 > 0:09:18For someone who's just joined the RAF,
0:09:18 > 0:09:21it would take nine months just to get to this point.
0:09:21 > 0:09:25Katy and Kiera have about two Hero Squad hours to learn what to do.
0:09:29 > 0:09:32Going down on the winch is the most dangerous role
0:09:32 > 0:09:34in any search and rescue exercise.
0:09:34 > 0:09:36The weather can be ferocious,
0:09:36 > 0:09:40and it's just the wire between you and a very long drop.
0:09:42 > 0:09:45- What would "winch in" be, do we think?- Winch in...
0:09:45 > 0:09:46Katy is controlling the winch,
0:09:46 > 0:09:51and Kiera is on the wire, for her very first helicopter rescue...
0:09:51 > 0:09:56Come up and go over your shoulders. One that way, one that way.
0:09:56 > 0:09:58And then this bit clips across the front.
0:09:58 > 0:09:59It is like a big nappy.
0:10:02 > 0:10:03..and she's going to be practising
0:10:03 > 0:10:07on a strapping, 190cm-tall RAF flight sergeant!
0:10:07 > 0:10:09Abseiling...
0:10:09 > 0:10:11No pressure, Kiera!
0:10:11 > 0:10:13Use good hand signals with the winch operator...
0:10:17 > 0:10:19Now, essentially, all you're going to do is winch in...
0:10:19 > 0:10:22The winch man has to be brave enough
0:10:22 > 0:10:25to go out of the door in a range of conditions
0:10:25 > 0:10:29and then he has to be able to keep himself safe,
0:10:29 > 0:10:31get himself to the casualty, and more importantly,
0:10:31 > 0:10:34keep the casualties safe and get them back up to the aircraft.
0:10:36 > 0:10:38They seem to both be doing very well.
0:10:38 > 0:10:40The control of the winch is good.
0:10:40 > 0:10:43I think our winchman is doing an admirable job
0:10:43 > 0:10:46of staying on her feet and getting the simulated casualty
0:10:46 > 0:10:49into the straps and back up to the aircraft. So, I'm very impressed.
0:10:49 > 0:10:51From what I've seen today, they're doing very well,
0:10:51 > 0:10:53and I'm sure we can find a job for them.
0:10:53 > 0:10:56That was so much fun!
0:10:56 > 0:10:59It feels really weird, though, cos you just see the helicopter
0:10:59 > 0:11:01go further and further away.
0:11:01 > 0:11:05It was, like, a really good feeling to just be in control.
0:11:05 > 0:11:07But I did think it was a bit of an ask
0:11:07 > 0:11:11to have a 12 and a 13-year-old who'd never seen a helicopter before.
0:11:11 > 0:11:13But I have to say, they did very well.
0:11:18 > 0:11:20Back in Snowdonia, mentor Chris and I
0:11:20 > 0:11:22are deciding who will be squad leader.
0:11:25 > 0:11:28This will be their most difficult rescue yet,
0:11:28 > 0:11:30and the squad leader must coordinate
0:11:30 > 0:11:33Hero Squad's first ever multi-agency rescue.
0:11:34 > 0:11:37By land, by air, by foot,
0:11:37 > 0:11:404 x 4 and helicopter,
0:11:40 > 0:11:43it's going to be a huge challenge.
0:11:50 > 0:11:52It's a biggie, it's a tough one, I'm not going to lie,
0:11:52 > 0:11:55and it's a big role for whoever's going to be the squad leader.
0:11:55 > 0:11:58From talking to Chris, we've both decided
0:11:58 > 0:12:01that the person that should be squad leader for tomorrow...
0:12:01 > 0:12:03is going to be you, Alex.
0:12:03 > 0:12:05- Well done.- Well done.
0:12:07 > 0:12:08Well done, Alex.
0:12:09 > 0:12:12Alex will lead the cadets into their last challenge.
0:12:13 > 0:12:17Alex has been on an incredible journey on Hero Squad,
0:12:17 > 0:12:19both as an individual and as a leader.
0:12:19 > 0:12:22He's shown great strength of character, and not only that,
0:12:22 > 0:12:26he's shown great physical strength too.
0:12:26 > 0:12:28There we go, there we go...
0:12:35 > 0:12:37It's Hero Squad rescue day.
0:12:39 > 0:12:41Two hikers are deep in the mountains of Snowdonia.
0:12:45 > 0:12:47They have reached the summit,
0:12:47 > 0:12:49when one of the walkers slips...
0:12:50 > 0:12:53Oh, Claire! Claire!
0:12:53 > 0:12:56She plummets over the edge of a cliff,
0:12:56 > 0:12:58banging her head on the way down.
0:12:58 > 0:13:00Paul, please get help! It really hurts!
0:13:00 > 0:13:03The Hero Squad casualty is stuck on a ledge.
0:13:06 > 0:13:09Her companion cannot reach her, and calls 999.
0:13:11 > 0:13:13I need Mountain Rescue...
0:13:13 > 0:13:17He's told to reply to a text, and with the help of SARLOC,
0:13:17 > 0:13:20the Mountain Rescue cadets now have a lock on his position.
0:13:22 > 0:13:24They are 20 miles away,
0:13:24 > 0:13:28and must traverse this treacherous terrain as fast as they can.
0:13:28 > 0:13:31Can Hero Squad come to the rescue one last time?
0:13:35 > 0:13:37It takes the cadets two hours
0:13:37 > 0:13:40to journey deep into the mountains in off-road vehicles.
0:13:46 > 0:13:49'Squad leader Alex uses SARLOC to calculate that
0:13:49 > 0:13:52'the witness is on the slope of a mountain 2km away...'
0:13:52 > 0:13:54Get moving...
0:13:55 > 0:13:58'..and he sends his foot search team to find him.'
0:13:58 > 0:14:00Good luck, guys!
0:14:09 > 0:14:13At RAF Valley, Katy and Kiera have started their first day
0:14:13 > 0:14:17as part of an RAF search and rescue crew.
0:14:17 > 0:14:21They are unaware of the unfolding Hero Squad emergency,
0:14:21 > 0:14:23but that is about to change.
0:14:25 > 0:14:27The foot search team has found the witness,
0:14:27 > 0:14:29and it's not good news.
0:14:29 > 0:14:31Do you know what happened?
0:14:31 > 0:14:34She went over the edge, and she's cracked her head...
0:14:34 > 0:14:37The news that this is a head injury changes everything.
0:14:38 > 0:14:40Control, this is Hero Squad One.
0:14:40 > 0:14:44He has said that there is a casualty down in the rocks
0:14:44 > 0:14:46and she has a head injury.
0:14:46 > 0:14:50That's a serious worry now, isn't it, from the first aid side of things?
0:14:50 > 0:14:53Look how long it's taken us to get in here.
0:14:53 > 0:14:55Especially with that long drive.
0:14:55 > 0:14:58If we've got a head injury, we've got serious problems to get her out.
0:14:58 > 0:15:00You can now decide if you need a helicopter
0:15:00 > 0:15:02to help us get this person out.
0:15:02 > 0:15:04Control, this is Hero Squad One.
0:15:04 > 0:15:08Can we just ask that we could have a helicopter, please?
0:15:08 > 0:15:10The casualty seems to have a head injury
0:15:10 > 0:15:13and that could be a serious risk to life, over.
0:15:13 > 0:15:15Hearing that, squad leader Alex
0:15:15 > 0:15:18puts in an immediate call to RAF Valley.
0:15:18 > 0:15:21PHONE RINGS
0:15:21 > 0:15:23C Flights...
0:15:23 > 0:15:26Hello, I'm Alex from Hero Squad. We're currently on a rescue
0:15:26 > 0:15:29and my team-mates need a helicopter...
0:15:29 > 0:15:34He's so focussed, he hasn't realised it's Katy and Kiera he's talking to.
0:15:34 > 0:15:38Is there any other information? What's happened to her?
0:15:38 > 0:15:41They've requested you because she's injured her head.
0:15:41 > 0:15:44But with the call logged, and the location confirmed,
0:15:44 > 0:15:46it's action stations!
0:15:46 > 0:15:48Once we all group together again,
0:15:48 > 0:15:51with two different parties coming together,
0:15:51 > 0:15:53I think it's going to be a really good final rescue.
0:15:53 > 0:15:55Hold onto your helmets!
0:15:55 > 0:15:59The rotors are turning, and for the RAF's two newest recruits,
0:15:59 > 0:16:00it's time for take-off!
0:16:03 > 0:16:05They are being piloted by their mentor,
0:16:05 > 0:16:07Squadron Leader Brassington.
0:16:07 > 0:16:12Kiera is being monitored by one of the RAF's most decorated winchmen,
0:16:12 > 0:16:14Master Aircrewman Richard Taylor.
0:16:15 > 0:16:19He's been involved in over 100 rescues
0:16:19 > 0:16:21and dozens of life-saving airlifts.
0:16:22 > 0:16:25Up in the air, it's Katy's job to monitor the radar and camera
0:16:25 > 0:16:28and identify any dangers on their flight path.
0:16:31 > 0:16:34That means helping to navigate a ten-tonne helicopter
0:16:34 > 0:16:37travelling at 120mph
0:16:37 > 0:16:39past dozens of potential hazards.
0:16:41 > 0:16:44Even in this foul weather, it takes them just 20 minutes
0:16:44 > 0:16:46to reach the rescue site
0:16:46 > 0:16:50compared to the three hours it took the Mountain Rescue teams.
0:16:50 > 0:16:52Back on the ground,
0:16:52 > 0:16:55Lewis is preparing to be lowered down 20 metres of vertical cliff
0:16:55 > 0:16:57towards the casualty.
0:16:57 > 0:16:59I'm down here!
0:17:00 > 0:17:02Luci and Andy are waiting at the bottom,
0:17:02 > 0:17:05ready to give emergency first aid.
0:17:05 > 0:17:09He's looking nervous, but he shouldn't be.
0:17:09 > 0:17:11Here we go! Keep going!
0:17:11 > 0:17:15All the way through Hero Squad, Lewis has shown great bravery.
0:17:15 > 0:17:19He overcame his fears during the terrifying lifeboat capsize...
0:17:19 > 0:17:21Well done!
0:17:21 > 0:17:23..and in cave rescue,
0:17:23 > 0:17:25when ropework and a dangerous rescue combined,
0:17:25 > 0:17:28he showed amazing courage.
0:17:28 > 0:17:31As brave as ever, Lewis is over the edge
0:17:31 > 0:17:32and on his way to the casualty.
0:17:32 > 0:17:34I'm just going to count you down...
0:17:40 > 0:17:43Once he's hooked the casualty onto his rope system,
0:17:43 > 0:17:45Lewis lowers her down to the stretcher team.
0:17:45 > 0:17:46Great work, Lewis.
0:17:46 > 0:17:48I've got a really bad headache!
0:17:48 > 0:17:51- She's clearly got an injury there, hasn't she?- Yeah.
0:17:51 > 0:17:52Luci takes over from here.
0:17:52 > 0:17:55Keep your neck nice and still, OK?
0:17:55 > 0:17:58It needs to be tight, OK? So it might be a bit uncomfortable...
0:17:58 > 0:18:01When it comes to caring for casualties,
0:18:01 > 0:18:04she's been the top Hero Squad cadet from the very start.
0:18:04 > 0:18:06It's OK!
0:18:06 > 0:18:09Whether it's been treating potential spinal injuries
0:18:09 > 0:18:12- in road traffic accidents... - Are you OK?
0:18:12 > 0:18:15..or treating hypothermia in lost walkers,
0:18:15 > 0:18:17she has always been first on the scene
0:18:17 > 0:18:20and done work a paramedic would be proud of.
0:18:20 > 0:18:23It's OK, we're just moving you into the back of the ambulance, OK?
0:18:26 > 0:18:27Control, this is Hero Squad One.
0:18:27 > 0:18:31We are just preparing the casualty for the helicopter
0:18:31 > 0:18:33and we will meet you in the landing zone.
0:18:35 > 0:18:37The helicopter is just minutes away.
0:18:37 > 0:18:40It's always a last resort for the crews
0:18:40 > 0:18:42to send out a winchman to pick up the casualty
0:18:42 > 0:18:44as it puts them both in danger.
0:18:46 > 0:18:48The Mountain Rescue team know this,
0:18:48 > 0:18:50and are taking the stretcher to a landing zone
0:18:50 > 0:18:52at the bottom of the hill at top speed.
0:18:57 > 0:18:59'The stretcher bearers meet with squad leader Alex
0:18:59 > 0:19:03'at the landing zone he's picked out for the helicopter.'
0:19:04 > 0:19:08That will do you, there. Well done. Excellent teamwork.
0:19:08 > 0:19:11The helicopter's on its way. It will be here in a few minutes.
0:19:15 > 0:19:18Helicopter 123, do you require smoke, over?
0:19:19 > 0:19:22We require smoke, helicopter 123.
0:19:22 > 0:19:23Roger that. Out.
0:19:23 > 0:19:24As squad leader,
0:19:24 > 0:19:27it's Alex who communicates directly with the RAF crew
0:19:27 > 0:19:28and guides the helicopter in.
0:19:28 > 0:19:31Here it comes, guys!
0:19:31 > 0:19:34OK, we're heading for the smoke over there, Kiera...
0:19:34 > 0:19:36On board, Katy is under pressure to guide the pilot
0:19:36 > 0:19:39and monitor the scene on the helicopter's camera system.
0:19:43 > 0:19:46The helicopter creates something called downdraft
0:19:46 > 0:19:48as it comes in to land.
0:19:51 > 0:19:53Hold onto your hats, cadets!
0:19:53 > 0:19:56This is the equivalent of being in a storm force gale.
0:19:56 > 0:20:00MUSIC: "Thunderstruck" by AC/DC
0:20:08 > 0:20:12The cadets have no idea who is going to get off this helicopter...
0:20:15 > 0:20:17..and it's a massive shock to them
0:20:17 > 0:20:20when they see that the first crew member on the ground
0:20:20 > 0:20:23is the RAF's newest winchperson, Kiera.
0:20:25 > 0:20:29I looked up and saw the other cadets' faces
0:20:29 > 0:20:31and they all had a massive smile on their faces
0:20:31 > 0:20:33and they waved at me and things.
0:20:34 > 0:20:37This 13-year-old is now the lead cadet
0:20:37 > 0:20:40and she must coordinate this daring land and air rescue.
0:20:42 > 0:20:46We've got a female who's fallen off a cliff, who has a head injury...
0:20:46 > 0:20:49From day one on Hero Squad, Kiera has shown
0:20:49 > 0:20:52incredible leadership skills for one so young...
0:20:53 > 0:20:56..taking charge on the treacherous mud flats...
0:20:56 > 0:20:59You all right, mate? We're going to get you out.
0:20:59 > 0:21:02..or rescuing people from the sea.
0:21:02 > 0:21:07Kiera has proved her ability and fearlessness time and again.
0:21:07 > 0:21:08'Good outcome. Standing by.'
0:21:10 > 0:21:13This head injury means the injured walker
0:21:13 > 0:21:15needs to get to hospital, and fast.
0:21:18 > 0:21:21Thinking on her feet, Kiera reminds the cadets
0:21:21 > 0:21:23to keep the casualty's head above her heart
0:21:23 > 0:21:26to prevent further blood loss.
0:21:26 > 0:21:28BOTH: Three, two, one, lift...
0:21:48 > 0:21:50As soon as she's on board
0:21:50 > 0:21:52Katy starts further treatment on the casualty.
0:22:00 > 0:22:03And when Kiera and Master Crewman Taylor give the signal
0:22:03 > 0:22:05it's time for take-off.
0:22:13 > 0:22:18The Hero Squad casualty is hurtling towards hospital and safety.
0:22:18 > 0:22:21We've got a patient we need to look after now.
0:22:21 > 0:22:24Within 20 seconds of flight, the Sea King Helicopter
0:22:24 > 0:22:28has covered the ground it took the mountain rescue cadets two hours
0:22:28 > 0:22:30to traverse by foot and 4x4.
0:22:30 > 0:22:34Maybe go and have a quick look over that ridge...
0:22:46 > 0:22:49For such an exhilarating rescue
0:22:49 > 0:22:51there are some long faces amongst the cadets.
0:22:51 > 0:22:54Doesn't take long, does it, to disappear?
0:22:55 > 0:22:58With the casualty safe, they think this is the end of
0:22:58 > 0:23:01their final Hero Squad rescue
0:23:01 > 0:23:05and that all that is left now is to pack up their equipment
0:23:05 > 0:23:08and face that long trek back to base.
0:23:10 > 0:23:13But I've got a little surprise for them.
0:23:13 > 0:23:15Sierra 123, receiving.
0:23:15 > 0:23:17We just realised it's a really long walk back to base
0:23:17 > 0:23:19and it's very bumpy in those Land Rovers...
0:23:19 > 0:23:22Any chance you could give us all a lift, over?
0:23:22 > 0:23:24What do you think, skipper?
0:23:24 > 0:23:25Yeah, I think we can do that.
0:23:25 > 0:23:27- KIDS:- Yes!
0:23:32 > 0:23:34I think they're happy with that.
0:23:36 > 0:23:38Having taken the casualty to safety
0:23:38 > 0:23:41the helicopter approaches the Hero Squad landing zone
0:23:41 > 0:23:45and the cadets are jumping for joy.
0:23:45 > 0:23:47We literally just ran everywhere.
0:23:47 > 0:23:49We were hugging each other and everything.
0:23:49 > 0:23:51We were really happy.
0:23:51 > 0:23:53We all started jumping around and Alice jumped
0:23:53 > 0:23:57on top of me. We were all so excited.
0:23:59 > 0:24:01OK, guys, 30 seconds to land.
0:24:07 > 0:24:09Katy's off the aircraft this time as well,
0:24:09 > 0:24:13and the whole of Hero Squad are finally reunited.
0:24:19 > 0:24:22It felt amazing to meet up with all the Hero Squad together,
0:24:22 > 0:24:25because it seemed like ages since we last saw them.
0:24:25 > 0:24:28It was amazing to update them on everything.
0:24:32 > 0:24:35The cadets board the helicopter for a ride that will take them
0:24:35 > 0:24:36to the end of Hero Squad.
0:24:39 > 0:24:43What a fantastic end to their journey this has been.
0:24:51 > 0:24:52I love it!
0:24:54 > 0:24:59This final rescue has been thrilling so far. Hopefully it won't end.
0:25:01 > 0:25:04Going on the helicopter today was absolutely amazing.
0:25:04 > 0:25:08It's by far been my favourite thing. Lost for words, it's amazing.
0:25:08 > 0:25:11It was awesome being on a helicopter,
0:25:11 > 0:25:14and I got to lean out, so there was the edge of the helicopter
0:25:14 > 0:25:16and I was like that. It was so cool.
0:25:19 > 0:25:21Working with the RAF has been amazing and I just want
0:25:21 > 0:25:23to go on and be an RAF cadet now
0:25:23 > 0:25:25and I'm going to when I get home.
0:25:27 > 0:25:30Being on that helicopter was amazing, cos the door opened
0:25:30 > 0:25:34and we got to look right out and it was like TV but real. It was weird.
0:25:38 > 0:25:41This whole experience has just been totally incredible
0:25:41 > 0:25:43and I just don't want it to end now.
0:25:46 > 0:25:50It's been really good on this whole Hero Squad experience
0:25:50 > 0:25:51and I wish it would never end.
0:25:53 > 0:25:57The final flight of the Hero Squad cadets is almost over.
0:25:57 > 0:26:01Over this epic series they've achieved so much,
0:26:01 > 0:26:04created some unforgettable moments,
0:26:04 > 0:26:07and impressed every member of the emergency services
0:26:07 > 0:26:09they've worked with.
0:26:09 > 0:26:13From all of us at the RNLI, well done, Hero Squad.
0:26:14 > 0:26:18You, Hero Squad, have done exceptionally well.
0:26:18 > 0:26:21You've shown leadership, communication and teamwork
0:26:21 > 0:26:23and done a really good job. Well done. Fantastic.
0:26:25 > 0:26:27If you take up caving seriously,
0:26:27 > 0:26:28there'll be a place on the team for you.
0:26:32 > 0:26:35Your work today here, cutting the guy out of the car, was first-class.
0:26:35 > 0:26:37You'd put a lot of fire stations to shame.
0:26:39 > 0:26:43It's not just the cadets' mentors who have sent their congratulations.
0:26:43 > 0:26:47When they reach the ground, there is a very special letter waiting for
0:26:47 > 0:26:50every single one of them, written and signed by the patron of
0:26:50 > 0:26:53the National Mountain Rescue Association
0:26:53 > 0:26:56and crew member of RAF 22 Squadron.
0:27:24 > 0:27:26That letter, that left me speechless.
0:27:26 > 0:27:28I just couldn't speak.
0:27:28 > 0:27:31It was actually Prince William who wrote the letter
0:27:31 > 0:27:32and signed it to us!
0:27:32 > 0:27:36No-one of 12 and 13 has got the chance to do
0:27:36 > 0:27:37all the stuff we've done.
0:27:37 > 0:27:40It's just been the best experience,
0:27:40 > 0:27:43and something you're never going to forget.
0:27:43 > 0:27:45I'm actually very, very proud of myself.
0:27:50 > 0:27:55Their journey with the emergency services and Hero Squad is over -
0:27:55 > 0:27:57or is it just the beginning?
