This is a former Eastern Airlines Martin 404 delivered January 23, 1953. Later with Southern Airways, it came to Florida Airlines via subsidiary Shawnee Airlines in 1977 as Southern ran into financial difficulties. Florida Airlines ran into financial problems itself as deregulation allowed majors to fly secondary routes, declaring bankruptcy in 1980. They flew their Martinliners during restructuring until the final shutdown in 1981. With Pro Air from 1983 - 89, the aircraft has been stored at Flying Tigers Airport outside Paris, TX since 1990.

It went to a museum at Toco (Flying Tiger Airport), Texas, in 1990. The museum closed circa 1997. The aircraft remained until at least 2015 (still in Pro Air cols). Fate since then is unknown.

Back with Florida Airlines from a lease to Air South with their titles removed.

This classic piston-engined airliner was seen at Atlanta amidst the jets.
