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,
Lilium Jet economical than the pure rotorcraft. The technical data are from the early phase of 2016. Lilium Jet The Lilium Jet is a proposed German vertical take-off and landing electrically powered light sport aircraft designed by Lilium GmbH. Lilium was founded in 2015 by four engineers and PhD students at the Technical University of Munich. They are supported by the Business Incubation Center Bavaria, the European Space Agency ESA, a Chinese Internet company, a bank, a technology fund and private investors. The Lilium Eagle, an unmanned two-seat proof of concept model, had its maiden flight at the airport Mindelheim-Mattsies near Munich
