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
Hawker Siddeley Harrier the more risky isolated approach. The first RAF squadron to be equipped with the Harrier GR.1, No. 1 Squadron, started to convert to the aircraft at RAF Wittering in April 1969. An early demonstration of the Harrier's capabilities was the participation of two aircraft in the "Daily Mail" Transatlantic Air Race in May 1969, flying between St Pancras railway station, London and downtown Manhattan with the use of aerial refuelling. The Harrier completed the journey in 6 hours 11 minutes. Two Harrier squadrons were established in 1970 at the RAF's air base in Wildenrath to be part of its air
