Lockheed Constellation

The Lockheed Constellation ("Connie") was a propeller-driven airliner powered by four 18-cylinder radial Wright R-3350 engines. It was built by Lockheed between 1943 and 1958 at its Burbank, California, facility. A total of 856 aircraft were produced in numerous models, all distinguished by a triple-tail design and dolphin-shaped fuselage. The Constellation was used as a civilian airliner and as a U.S. military air transport, seeing service in the Berlin Airlift. It was the presidential aircraft for U.S. President Dwight D. Eisenhower.
