The Convair CV-240 first took to the skies in 1947 and went on to become a mainstay in airline fleets across the world. The CV-240 went through several generations, starting as an unpressurized 30-seat aircraft and evolving into a 52-seat turboprop. In total, more than 1,000 CV-240s were built across the different variants until production ended in 1954.
