Douglas C-54 Skymaster
Douglas developed the DC-4 in response to requests from Eastern and United Airlines, after the failed DC-4E, which proved too complicated and uneconomical.
Before the type entered production World War Two broke out and all contracts were taken over by the USAF, designating the aircraft as C-54; US Navy gave it the designation R5D.
The first C-54 made its first flight on 14 February 1942. 1163 Examples were built between 1942 and 1946. After the war a further 79 DC-4s were built.
After the war the type was developed into the larger DC-6 and DC-7.
