The Lockheed Constellation ("Connie") is a propeller-driven, four-engined airliner built by Lockheed Corporation starting in 1943. The Constellation series was the first pressurized-cabin civil airliner series to go into widespread use. Its pressurized cabin enabled commercial passengers to fly well above most bad weather for the first time, thus significantly improving the general safety and ease of air travel.
The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles.
The Boeing C-97 Stratofreighter was a long-range heavy military cargo aircraft developed from the B-29 and B-50 bombers. Design work began in 1942, the first of three prototype XC-97s flew on 9 November 1944 and the first of six service-test YC-97s flew on 11 March 1947. All nine were based on the 24ST alloy structure and Wright R-3350 engines of the B-29, but with a larger-diameter fuselage upper lobe and they had the B-29 vertical tail with the gunner's position blanked off. The first of three heavily revised YC-97A incorporating the re-engineered wing, taller vertical tail and larger Pratt & Whitney R-4360 engines of the B-50 bomber, flew on 28 January 1948 and was the basis of the subsequent sole YC-97B, all production C-97s, KC-97s and civilian Stratocruiser aircraft. Between 1944 and 1958, 888 C-97s in several versions were built, 811 being KC-97 tankers. C-97s served in the Berlin Airlift, the Korean War, and the Vietnam War. Some aircraft served as flying command posts for the Strategic Air Command, while others were modified for use in Aerospace Rescue and Recovery Squadrons (ARRS).
The Lockheed EC-121 Warning Star was an American airborne early warning and control radar surveillance aircraft operational in the 1950s in both the United States Navy (USN) and United States Air Force (USAF).
The 1254th Air Transport Wing was a United States Air Force unit, existing between 1948 and 1966. It was last stationed at Andrews AFB, Maryland.
Trek Airways was an airline based in South Africa that operated from August 1953 until April 1994.
The Pratt & Whitney T34 was an American axial flow turboprop engine designed and built by Pratt & Whitney. Its only major application was on the Douglas C-133 Cargomaster.
Clarence Leonard "Kelly" Johnson was an American aeronautical and systems engineer. He is recognized for his contributions to a series of important aircraft designs, most notably the Lockheed U-2 and SR-71 Blackbird. Besides the first production aircraft to exceed Mach 3, he also produced the first fighter capable of Mach 2, the United States' first operational jet fighter, as well as the first fighter to exceed 400 mph, and many other contributions to various aircraft.
The Lockheed C-69 Constellation was a four-engined, propeller-driven military transport aircraft developed during World War II. It was co-developed with the Lockheed Constellation airliner.
The Lockheed L-1649 Starliner was the last model of the Lockheed Constellation line of airliners. Powered by four Wright R-3350 TurboCompound engines, it was built at Lockheed's Burbank, California plant from 1956 to 1958.
The Boeing C-137 Stratoliner is a retired VIP transport aircraft derived from the Boeing 707 jet airliner used by the United States Air Force. Other nations also bought both new and used 707s for military service, primarily as VIP or tanker transports. In addition, the 707 served as the basis for several specialized versions, such as the E-3 Sentry AWACS aircraft. The designation C-18 covers several later variants based on the 707-320B/C series. The C-137 should not be confused with the similar Boeing C-135 Stratolifter; although they share a common ancestor the two aircraft have different fuselages, among other structural differences.
The Lockheed L-1049 Super Constellation is an American aircraft, a member of the Lockheed Constellation aircraft line. Colloquially referred to as The Connie.
The Lockheed L-049 Constellation was the first model of the Lockheed Constellation aircraft line. It entered service as the C-69 military transport aircraft during World War II for the United States Army Air Forces and was the first civilian version after the war. When production ended in 1946 it was replaced by the improved L-649 and L-749 Constellation.
The Lockheed L-649 Constellation was the first real civilian version of the Lockheed Constellation line, as the Lockheed L-049 Constellation was a simple redesign from the military Lockheed C-69 Constellation. The L-649 was planned to be the new standard version of the Constellation, but the L-749 Constellation, a co-jointly produced improved derivative, was chosen over the L-649 by most airlines. Most of the few L-649 aircraft built were delivered and operated by Eastern Air Lines.
The Lockheed L-749 Constellation is the first Lockheed Constellation to regularly cross the Atlantic Ocean non-stop. Although similar in appearance to the L-649 before it, the L-749 had a larger fuel capacity, strengthened landing gear, and eventually weather radar.
The Lockheed L-1249 Super Constellation was a turboprop-powered version of the Lockheed Constellation aircraft family. Built in 1954 and 1955, the aircraft were used as prototypes for possible future military transport aircraft for both the United States Air Force and United States Navy. Both aircraft saw very short lives and the airframes were later used to build L-1049 Super Constellations.
Columbine II is a Lockheed VC-121A-LO Constellation ; the aircraft that was to become the first plane to use the Air Force One callsign and the only presidential aircraft ever sold to a private party. The aircraft was ferried from long-term storage in the Sonoran Desert at Marana Regional Airport, Arizona, to the east coast for restoration in March 2016.
