Originally this C-119 was US Air Force 48-322. Becoming N13475 when it was used by Aero Union and later, Hemet Valley Flying Service as a fire fighting air tanker, it had a Steward-Davis jet-pack conversion utilizing a Westinghouse J34 engine added to the fuselage. The registration was cancelled in 1995 and the aircraft went on display at the Milestones of Flight Air Museum, Fox Field, Lancaster, CA where it remains today.
