Built

Boeing built the C-97 by putting a two-storey fuselage on the wings and tail of the B-29, and most of the 888 built were KC-97 tankers that refuelled Strategic Air Command's jets through the 1950s. The problem was that a piston tanker could barely keep up with a jet bomber, so the KC-97L got two extra jet engines under the wings. Its airliner twin was the Stratocruiser. A single KC-97L still flies, with the Berlin Airlift Historical Foundation.

Fun fact

The KC-97L carried six engines: four big radials and two jet pods borrowed from the F-86, bolted on so it could refuel jets without stalling.

How to spot one

A huge, deep fuselage with a figure-eight cross-section, four radials, and a tall single fin. The KC-97L carries a jet pod under each outer wing.
