Video The Airlander 10 hybrid – part airplane and part airship – has had a bumpy touchdown after piling into its landing site nose first.

The 92-meter 302-foot aircraft gets 60 per cent of its lift from the helium that fills its two massive airbags, which have earned the aircraft its nickname of the Flying Bum, although the manufacturers call it the Martha Gwyn.

The remaining lift comes from its small wings and aerodynamic shape, powered by four turbocharged diesel engines.
