The World's largest Aircraft named Airlander
left it's hangar for the first time today.
The Aircraft which is about 92 metres long and 302ft long aand is about 50ft larger than the biggest passenger jets
Airlander was at first developed for the US government as a long endurance surveillance aircraft but it fell foul of defence cutbacks.
Airlander has now formally been granted permission to conduct its first series of flight tests by both European Aviation Safety Agency and the UK Civil Aviation Authority.
The project's technical director, Mike Durham, said:
Last week we successfully completed our final in-hangar all engines, all generators, all systems testing.
'My thanks to the whole business for getting us here. The entire team is looking forward to the final series of tests outside before taking to the skies for the first time.
Airlader will have the ability to fly about 4,000 ft at speeds of close to 46 mph in a series of 6 test flights above Cardington, Bedfordshire
More images to show how big this Aircraft is.
The Airlander 10, which cost £25million to build over 10 years, is 92 metres long and pumped with a million cubic feet of helium.
Now that's big!
