History Martin Aircraft Company
Martin 2.0.2 / 4.0.4 models
Glenn L. Martin, president of the company, intended that the Model 2-0-2 would be a replacement for the Douglas DC-3. It was also known as the "Martin Executive".
The first flight of the model was in November 1946. Full civilian certification was gained in August 1947, several months before competing aircraft types. The total production of 2-0-2s and 2-0-2As was 47 aircraft. The aircraft was not pressurized, but was considered a long-range airliner. The fatal crash in 1948 of Northwest Airlines Flight 421 revealed a serious structural problem in the wings. Structural metal fatigue was the problem in a major wing spar.
The Martin 4-0-4 was an American pressurized passenger airliner built by the Glenn L. Martin Company. In addition to airline use initially in the United States, it was used by the United States Coast Guard and United States Navy as the RM-1G (later as the VC-3A).
