The very first Convairliner, first flown as NX90849 from Lindbergh Field in San Diego on March 16th 1947. Subsequently registered to various corporate owners as N24501, N112G, N192L and N195L and finally N240BN in 1976. Notably, in 1950 as N24501. the aircraft was converted to a Convair 240-21 with two Allison 501 turboprops and became the first turboprop airliner to fly in the USA. Later converted back to piston power, and despite surely being an airframe worthy of preservation, the aircraft was sadly scrapped after several years of storage at Opa Locka.
