The Aircraft

The post-war grail for aircraft manufacturers was to develop a replacement for the Douglas DC-3.  Martin's entry into this perceived market was the Martin 4-0-4 series of aircraft.

The prototype 2-0-2 first flew on 22 November 1946.  The loss of a 2-0-2 in 1948 due to wing structural failure led to the end of production for this aircraft.  An improved 3-0-3 had already been flown but the need for a wing redesign put an end to the 3-0-3 also.

The 4-0-4 had a redesigned wing as well as a pressurized cabin.  The delay allowed other manufacturers the lead time they needed.  Production of the 4-0-4 ended in 1953 after only 103 had been built.
