EWR VJ 101 the VJ 101C did not proceed to production status, various other projects of the era to develop supersonic-capable VTOL fighter aircraft, including the Mirage IIIV and the Hawker Siddeley P.1154 (a supersonic parallel to what would become the Hawker Siddeley Harrier, a subsonic VTOL combat aircraft that reached operational service), ultimately met similar fates. The Harrier jump jet and, substantially later, the Lockheed Martin F-35 Lightning II, has since demonstrated the potential of VTOL fighters. EWR VJ 101 The EWR VJ 101 was an experimental German jet fighter vertical takeoff/landing (VTOL) tiltjet aircraft. VJ stood for "Versuchsjäger", (German for "Experimental
Maurice Brennan assistant chief engineer working with Barnes Wallis on variable-geometry aircraft projects that would eventually become the basis of the AFVG project. However, he resigned again after ten months, joining Folland in 1960, replacing Teddy Petter as director and chief engineer. By this time Folland was part of Hawker Siddley, and he was responsible for developing the two-seat Gnat T.1, various twin engined and variable wing geometry Gnat proposals and the GERM hovercraft project (Ground Effect Research Machine). In 1961 he moved to Avro (also part of Hawker Siddley) succeeding Roy Ewans as a director and chief engineer. From 1961-1969 his
