One of 224 Packets built for the USAF (as 44-23033), of which about half were offered to the civil market from 1954, some undergoing Jet-Pak conversion by Steward-Davies with the addition of a J34 jet on top of the fuselage. Without this, the aircraft's engine-out performance was virtually zero. This one was not converted and was last registered to New Frontier Airlift Corp in Feb 1962, although still in USAF marks when seen here. Wreck noted during 2001 at Davis-Monthan in the yard of National Aircraft, Kolb Rd.
