Airlander 10, the world's largest aircraft, has crashed during its second test flight since being revamped in the UK.

The aircraft, nicknamed the "Flying Bum" because of its evocative shape, came down to the earth with a bump at its base at Cardington airfield in Bedfordshire.

Pictures show it nosedived near the end of the flight. No one was injured.

The aircraft - which is part plane, part helicopter and part airship and measures 302ft-long (92m) - is reported to have been damaged at both its front and sides.

A spokesman for Hybrid Air Vehicles (HAV), which is developing Airlander 10, said: "Airlander sustained damage on landing during today's flight."


He added: "We're debriefing following the second test flight this morning. All crew are safe and well, and there are no injuries."

The first test flight was carried out last Thursday, with crowds cheering as the airship performed a lap around the airfield.

The makers hoped the successful first test flight would be the start of a series which would ultimately allow a manned aircraft to remain airborne for around five days.

The airship was developed to be used by the US as a long-range surveillance machine but defence cuts meant it was not destined for take-off.

It is about 50ft (15m) longer than the world's largest passenger jet, uses helium to take flight and can travel at speeds of up to 92mph.

HAV hope an Airlander 50 will eventually be developed, allowing it to transport 50 tons of freight.
