The Airlander 10 hybrid airship, known in Britain as 'the flying bum' because of its unique structure, makes its maiden flight at Cardington Airfield in UK, August 17, 2016.  Purchased by UK-based aviation company Hybrid Air Vehicles in 2013, the 302-foot (92 meters) helium-filled airship was originally developed for the US Army as a spy aircraft to hover over war zones for weeks using only a fraction of the fuel needed by conventional aircraft.
