Masquerading as a civilian airliner during the mid-1930s, the Heinkel He
111 medium-range bomber saw its first combat in 1936 with Germany's
Condor Legion during the Spanish Civil War. The initial stages of World
War II confirmed the design's prominent role in advancing the German
blitzkrieg in Poland and France. However, it was during the 1940-41 air
battles over Britain that the type's defensive shortcomings became
apparent. Easily recognized with its "greenhouse" nose, the He 111 was
one of the most widely used Luftwaffe aircraft of WWII and saw use as a
bomber and transport over nearly every warfront. Later models were
successfully used in antishipping and glider tug roles. A postwar model,
the CASA 2.111, was flown by Spain's air force until the late 1950s, and
as a transport into the 1970s. These Spanish models were also seen in
such classic war films at The Battle of Britain and Patton.
