The Williams X-Jet , created by Williams International , was a small, single-person, light-weight, Vertical Take Off and Landing ( VTOL ) aircraft powered by a modified Williams F107 turbofan aircraft engine — designated WR-19-7 — after some minor modifications. The vehicle was nicknamed "The Flying Pulpit " for its shape. It was designed to carry one operator and to be controlled by leaning in the direction of desired travel and by modulating engine output power. It could move in any direction, accelerate rapidly, hover and rotate on its axis, stay aloft for up to 45 minutes and travel at speeds up to 60 miles per hour (97 km/h). It was evaluated by the United States Army in the 1980s, but was deemed inferior to the capabilities of helicopters and small, uncrewed aircraft, and so the development of the X-Jet was discontinued.

15-518: Is designated WR19-7, rated at 570 lbf thrust, after minor modifications and said derating. Modifications to the WR-19-A7D included accessories — replacement of pyro starter with electric/air start — and exhaust system modifications. No internal modifications to the counter-rotating micro turbofans were performed. The first crewed, untethered flight was conducted in April 1980. Ray Le Grande
