A Boeing C-97 Stratofreighter of the U.S. Air Force sits on the ramp in this mid-century photograph. Derived from the Boeing 377 Stratocruiser airliner and sharing wings and engines with the B-50 Superfortress bomber, the C-97 served as a long-range cargo and personnel transport - and, in tanker form, as an aerial refueler - throughout the 1950s and 1960s.
