Airlander 10 was originally developed as part of a US Army project which was then abandoned in 2012

A British company is now converting the aircraft - a cross between an airship and an aeroplane - into civilian use

It recently took off inside its hangar in Bedfordshire for the first time so engineers could add the finishing touches

Engines and fins are being fitted this week and the 300-ft (93 metre) craft will make its debut test flight next month
