Designed for research into supersonic propeller design, the XF-88B flew for the first time on 14 April 1953. Power was provided by two Westinghouse J34 turbojets and a nose-mounted Allison XT38 turboprop engine.

George, the aircraft that you saw was probably a Pilatus PC 12. business aircraft. the nose profile is very similar. The XF-88 was purely experimental and never intended for operational service use.
