The DC-4 entered service with Eastern and Untied pre-WWII in 1939. However they proved to be complicated to maintain and not efficient enough for commercial service. Eastern and United requested a different aircraft be developed that was simpler and smaller than the DC-4 then in service. However the Japanese attack on Pearl Harbor brought the US into WWII. The production of DC-4s was turned over to the military and 1100 C-54s and R5Ds were produced during the war. Another 79 DC-4s were produced for the airlines after the war while many C-54s and R5Ds were returned to civilian commercial use. These aircraft carried about 40 to 80 passengers and had a crusing speed of 227 mph. It had a range of 4250 miles and a service ceiling of 22300 feet. There remain DC-4s in service as of 2014.
