Convair 240

The Convair 240 was a twin-engine, propeller-driven airliner introduced by Consolidated Vultee Aircraft (Convair) in the late 1940s. Unveiled in 1947, it was developed as a modern, pressurized replacement for the ubiquitous Douglas DC-3 on short- and medium-haul routes, offering passengers a more comfortable and faster cabin experience.

Powered by two Pratt & Whitney radial engines, the Convair 240 could cruise at around 300 miles per hour while carrying roughly forty passengers. American Airlines was among the launch operators, placing the type into commercial service in 1948. Its pressurized cabin allowed it to fly above much of the weather that troubled older, unpressurized airliners.

The 240 launched a successful family of Convair-Liner aircraft, followed by the larger and improved Convair 340 and 440 models. These airliners became a common sight on regional routes around the world during the 1950s, and many examples enjoyed long second careers with smaller carriers and as cargo and utility aircraft.
