A Boeing C-97 Stratofreighter of the California Air National Guard, tail number 00697, sits on the ramp with 'CALIF. AIR GUARD' proudly displayed on its nose. Powered by four Pratt & Whitney R-4360 radial engines and derived from the B-29 Superfortress, the C-97 gave the Guard heavy-lift transport capability throughout the late 1950s and 1960s.
