:00:00. > :00:08.It's Friday, I'm Ayshah and we're live with the world's biggest
:00:09. > :00:15.aircraft ever on the way. And Barack Obama's White House workout. This is
:00:16. > :00:18.Newsround. First today, we've been speaking to Ukrainian kids here in
:00:19. > :00:23.the UK about what's happening to their country. We'll hear from them
:00:24. > :00:27.in a minute. It's been another fast-moving day already over there.
:00:28. > :00:30.Neighbouring Russia has denied taking control of two airports in
:00:31. > :00:33.the south, and the former Ukrainian President has spoken for the first
:00:34. > :00:39.time since leaving the Eastern European country, saying he was
:00:40. > :00:42.forced out of power. The crisis started back in November with
:00:43. > :00:46.clashes between people who wanted Ukraine to make a deal with the
:00:47. > :00:50.European Union and those who thought it should stay closer to Russia.
:00:51. > :00:53.Thousands marched to Kiev's main square to make their point, but
:00:54. > :00:59.earlier this month, demonstrations turned violent and several people
:01:00. > :01:02.died. Since then, the violence has spread from Kiev to Crimea in the
:01:03. > :01:06.south, and the country's become more divided. So what's it like to see
:01:07. > :01:13.that happening to your country? Nel's been speaking to Sophia and
:01:14. > :01:18.Ilia to find out. You When I saw what happened in Kiev, I start
:01:19. > :01:27.crying so much, because I remember it was a beautiful city. It's got
:01:28. > :01:32.lots of big buildings and streets but now it's all wrong. It's
:01:33. > :01:37.horrible what's happened now. Everything was clean. But now the
:01:38. > :01:42.buildings are just smashed and it's like the olden days. It's like after
:01:43. > :01:46.war. Were you worried at all when you started seeing all of the
:01:47. > :01:52.pictures and news stories about the Ukraine? I'm worried so much because
:01:53. > :01:57.my family in Ukraine, my mum said it's going to be war in Ukraine,
:01:58. > :02:00.just for nothing, because the people want to have a good future for
:02:01. > :02:06.themselves. I'm worried because like, more than 100 people got got
:02:07. > :02:11.killed. Are your hopes for the future? I want to live in Ukraine. I
:02:12. > :02:18.want to have children. I want to live in a free country. I don't want
:02:19. > :02:21.peoplifying -- fighting. I hope that the buildings are clean and built up
:02:22. > :02:29.and everything and everyone has a better future.
:02:30. > :02:32.The trial badger culls, that took place in England last year, didn't
:02:33. > :02:35.work in the way they were supposed to, according to scientists who've
:02:36. > :02:39.looked into the issue. The aim of the culls was to help stop the
:02:40. > :02:43.spread of a disease called TB that was affecting cows. A new report's
:02:44. > :02:46.found that the number of badgers killed fell short of the target, and
:02:47. > :02:50.that the way they were killed was sometimes inhumane. On to the
:02:51. > :02:53.biggest story of the day now - Quite literally! The largest aircraft in
:02:54. > :02:57.the world ever has been shown off for the first time today. It's got
:02:58. > :03:02.all kinds of cool features and could even help to take aid to people in
:03:03. > :03:06.need. Part plane, part airship, part helicopter. This is the world's
:03:07. > :03:10.longest flying machine. It has a giant helium-filled balloon with an
:03:11. > :03:13.aerodynamic shape, so it can generate lift. The team behind it
:03:14. > :03:17.boasts it can stay in the air for three weeks and it could potentially
:03:18. > :03:21.carry hundreds of people. I want to get in this thing and fly it pole to
:03:22. > :03:28.pole. We will fly over the Amazon at 20 feet. We will fly over the
:03:29. > :03:31.world's greatest cities. We will show the whole world live on the
:03:32. > :03:36.internet how beautiful this planet is. They say it could do a lot of
:03:37. > :03:39.practical good. Its size and the fact it can land pretty much
:03:40. > :03:44.anywhere, even on water means that it could be used to deliver vital
:03:45. > :03:50.aid to disaster zones. Just how big is this aircraft? It's 92 metres
:03:51. > :03:54.long, that's almost 20 metres longer than the biggest airliner. It's
:03:55. > :03:59.equal to more than nine double-decker buses lined up and 57
:04:00. > :04:02.of me lying down. The first UK flight is set to take off later this
:04:03. > :04:06.year. Next, one of our favourite stories
:04:07. > :04:08.of the week is all over the newspapers and the web today:
:04:09. > :04:12.18-year-old Southampton footy player Luke Shaw phoning his mum and
:04:13. > :04:15.bursting into tears of joy, after he found out he'd been picked for the
:04:16. > :04:19.latest England squad. So we've been asking you on the Newsround website,
:04:20. > :04:22.what you've done to make your parents proud. Olivia says "I made
:04:23. > :04:27.my parents proud when I first went to the dentist when I was six."
:04:28. > :04:30.Jessica says it was when she got a certificate in assembly. And Samet
:04:31. > :04:33.says, "My parents are proud of me because I'm so good at football and
:04:34. > :04:37.maths." Good on you. Finally, Barack Obama as you've never seen him
:04:38. > :04:40.before. This is the US President and his second in command Joe Biden
:04:41. > :04:44.jogging through the White House for their own fitness video. It's all
:04:45. > :04:48.for a special campaign, from his wife Michelle, to try and get kids
:04:49. > :04:53.healthier. That is it. Head over to the website to check out stunning
:04:54. > :04:55.pictures of the Northern Lights. Newsround is back tomorrow.
