Lockheed Constellation

Family of US airliners with 4 piston engines, 1943

The Lockheed Constellation ("Connie") is a propeller-driven, four-engined airliner built by Lockheed Corporation starting in 1943. The Constellation series was the first civil airliner family to enter widespread use equipped with a pressurized cabin, enabling it to fly well above most bad weather, thus improving the general safety and ease of commercial passenger air travel. Several models of the Constellation series were produced, all with the distinctive triple tail and dolphin-shaped fuselage.
