Hybrid Air Vehicles Airlander 10

The Hybrid Air Vehicles Airlander 10 (originally developed as the HAV 304; nicknamed "The Flying Bum") is a hybrid airship designed and built by British manufacturer Hybrid Air Vehicles (HAV). Comprising a helium airship with auxiliary wing and tail surfaces, it flies using both aerostatic and aerodynamic lift and is powered by four diesel engine-driven ducted propellers. The HAV 304 was originally built for the United States Army's Long Endurance Multi-intelligence Vehicle (LEMV) programme. Its maiden flight took place in 2012 at Lakehurst, New Jersey, in the US. In 2013, the LEMV project was cancelled by the US Army. HAV reacquired the airship and brought it back to Cardington Airfield in England. It was reassembled and modified for civilian use, and in this form was redesignated the Airlander 10. The modified aircraft completed design certification testing before being written off when it came loose from its moorings...
