Harrier Jump Jet two systems are fully interlinked but air is not supplied to the reaction control valves during conventional wingborne flight. Harrier Jump Jet The Harrier, informally referred to as the Harrier Jump Jet, is a family of jet-powered attack aircraft capable of vertical/short takeoff and landing operations (V/STOL). Named after a bird of prey, it was originally developed by British manufacturer Hawker Siddeley in the 1960s. The Harrier emerged as the only truly successful V/STOL design of the many attempted during that era, despite being a subsonic aircraft, unlike most of its competitors. It was conceived to operate from improvised bases,
Aurora Flight Sciences carrying a payload: Aurora proposed three drones taking off separately then joining up in flight, to form an efficient flat wing at night, and folding into a Z for the best solar energy collection in daylight. In 2009, as Aurora has developed its own line of small vertical take-off UAVs known as the Aurora Goldeneye, the third variant of this family, the GoldenEye-80, was first flown publicly at Association for Unmanned Vehicle Systems International's Unmanned Systems North America trade show. On October 5, 2017 Boeing announced that it would be acquiring Aurora Flight Sciences. In April 2018, as DARPA allowed
