A giant hybrid airship which is being built in Bedfordshire has taken a step closer to completion.
A fin has been lifted into place and attached to the hull of the Airlander which is being built in a hangar at Cardington.
Other fins and the engines will be fitted in the coming weeks.
The Airlander is said to be the largest aircraft in the world and is designed to remain in the air for weeks at a time.
The world's largest aircraft, known fondly as the 'Flying Bum', has been officially named by the Duke of Kent in Bedfordshire.
The world's largest aircraft has been unveiled for the first time since being fully assembled in the UK.
A multi-million pound campaign to relaunch Britain's Airship industry in the Bedfordshire countryside has begun.
