The world's largest aircraft is in final preparations for its second phase of test flights.
The Airlander 10 has been built in a huge hangar in Bedfordshire - but it's starting to outgrow its home at Cardington Airfield.
Next year, it will move to a new site - Sarah Byrd's been finding out where it might be going.
Technical problems stopped the world's biggest aircraft making its maiden flight this evening.
The Airlander airship has been created at the Cardington Hangars in Bedfordshire.
It was all set for its first flight earlier - with hundreds of people turning out to watch.
Organisers got as far as starting their engines but delays with the take off meant there was not enough light left to do the flight.
