DC-4
THE DC-4 was a four-engine propeller developed by the Douglas Aircraft Company to replace the
successful DC-3.The first model was
created in 1938 and could carry 42 passengers. It was intended to fulfill United
Airlines' requirement for a long-range passenger airline, but It was not put into commercial
service until 1946. In 1942 he ordered the military
version known as C-54 ordered by the
US Army Air Force. After World War
II, commercial airlines placed more than 300 civilian DC-4 transports into
service.
The
special feature was the fuselage of unusually
wide cross-section for its day and a triple fin tail unit,
similar to that later used by Lockheed
on its Constellation. The DC-4's tricycle landing gear allowed its
fuselage to be constant cross-section for most of its length, so it could be
easily stretched into the later DC-6 and DC-7.
