In February 1961 the aircraft was original delivered to American Airlines, registered as N7538A and named Idaho. In the early sixties Astrojet was the type name given by American Airlines to all their jet aircraft. In September 1972 the aircraft was sold to Middle East Airlines and registered as OD-AFQ.

Early in 1986 the aircraft was acquired by the engine manufacturer and has since been used to flight test a variety of of engines. Turboshaft engines like PT6, PW100 and PW150 have been fitted in the extended nose; the PW306, PW308, PW530, PW545 and PW615 in the nacelle behind the cockpit and the huge IAE2500 on a special pylon."
