19420214: The Douglas DC-4 Skymaster made its initial flight, thereafter becoming prominent in a generation of four-engine U.S. transports that advanced long-haul air travel. The plane was a scaled-down version of a prototype developed in 1939. The DC-4 carried a crew of six and up to forty-two passengers. Unlike the Boeing 307 and 307B, it did not have a pressurized cabin. The DC-4 entered military transport service with the military designation of C-54.
19630214: The Civil Aeronautics Board disapproved agreements reached by the International Air Transport Association at its Chandler, Ariz., conference the previous fall to increase certain passenger fares on North Atlantic and Pacific routes. The CAB stand for lower fares resulted in a major controversy among international air carriers and their governments.
