Template:Short description Template:Infobox aircraft 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 significantly improving the general safety and ease of commercial passenger air travel.<ref>Historic airliner trucked 300 miles to be a hotel bar CNN Travel. By Thom Patterson. 13 October 2018. Downloaded Oct. 21, 2018.</ref>

Several different models of the Constellation series were produced, although they all featured the distinctive triple-tail and dolphin-shaped fuselage. Most were powered by four 18-cylinder Wright R-3350 Duplex-Cyclones. In total, 856 were produced between 1943 and 1958 at Lockheed's plant in Burbank, California, and used as both a civil airliner and as a military and civilian cargo transport. Among their famous uses was during the Berlin and the Biafran airlifts. Three served as the presidential aircraft for Dwight D. Eisenhower, one of which is at the National Museum of the United States Air Force.

Design and developmentEdit

Initial studiesEdit

Lockheed had been working on the L-044 Excalibur, a four-engined, pressurized airliner, since 1937. In 1939, Transcontinental and Western Airlines (TWA), at the instigation of major stockholder Howard Hughes, requested a 40-passenger transcontinental airliner with a range of Template:Convert<ref name=Jane1993>Template:Harvnb</ref>—well beyond the capabilities of the Excalibur design. TWA's requirements led to the L-049 Constellation, designed by Lockheed engineers, including Kelly Johnson and Hall Hibbard.<ref name=yenne>Template:Harvnb</ref> Willis Hawkins, another Lockheed engineer, maintains that the Excalibur program was purely a cover for the Constellation.<ref name=boyne>Template:Harvnb</ref>

Development of the ConstellationEdit

The Constellation's wing design was close to that of the Lockheed P-38 Lightning, differing mostly in size.Template:Sfn The triple tail allowed the aircraft to fit into existing hangars,<ref name=boyne /> while features included hydraulically boosted controls and a deicing system used on wing and tail leading edges.<ref name=Jane1993 /> The aircraft had a maximum speed over Template:Convert, faster than that of a Japanese Zero fighter, a cruise speed of Template:Convert, and a service ceiling of Template:Convert.

According to Anthony Sampson in Empires of the Sky, Lockheed may have undertaken the intricate design, but Hughes's intercession in the design process drove the concept, shape, capabilities, appearance, and ethos.Template:Sfn These rumors were discredited by Johnson. Howard Hughes and Jack Frye confirmed that the rumors were false in a letter dated November 1941.Template:Sfn

Operational historyEdit

World War IIEdit

With the onset of World War II, the TWA aircraft entering production were converted to an order for C-69 Constellation military transport aircraft, with 202 aircraft intended for the United States Army Air Forces (USAAF). The first prototype (civil registration NX25600) flew on January 9, 1943, a short ferry hop from Burbank to Muroc Field for testing.<ref name=Jane1993 /> Edmund T. "Eddie" Allen, on loan from Boeing, flew left seat, with Lockheed's own Milo Burcham as copilot. Rudy Thoren and Kelly Johnson were also aboard.

Lockheed proposed the model L-249 as a long-range bomber. It received the military designation XB-30, but the aircraft was not developed. A plan for a very long-range troop transport, the C-69B (L-349, ordered by Pan Am in 1940 as the L-149),<ref name="Stringfellow and Bowers" /> was cancelled. A single C-69C (L-549), a 43-seat VIP transport, was built in 1945 at the Lockheed-Burbank plant.

The C-69 was mostly used as a high-speed, long-distance troop transport during the war.Template:Sfn In total, 22 C-69s were built before the end of hostilities, but seven of these never entered military service, as they were converted to civilian L-049s on the assembly line. The USAAF cancelled the remainder of the order in 1945. Some aircraft remained in USAF service into the 1960s, serving as passenger ferries for the airline that relocated military personnel, wearing the livery of the Military Air Transport Service.

Postwar useEdit

After World War II, the Constellation came into its own as a fast civilian airliner. Aircraft already in production for the USAAF as C-69 transports were finished as civilian airliners, with TWA receiving the first on 1 October 1945. TWA's first transatlantic proving flight departed Washington, D.C., on December 3, 1945, arriving in Paris on December 4 via Gander and Shannon.<ref name=Jane1993 />

TWA transatlantic service started on February 6, 1946, with a New York-Paris flight in a Constellation. On June 17, 1947, Pan American World Airways (Pan Am) opened the first-ever scheduled round-the-world service with its L-749 Clipper America. The famous flight "Pan Am 1" operated until 1982.Template:Citation needed

As the first pressurized airliner in widespread use, the Constellation helped establish affordable and comfortable air travel. Operators of Constellations included TWA, Eastern Air Lines, Pan Am, Air France, BOAC, KLM, Qantas, Lufthansa, Iberia Airlines, Panair do Brasil, TAP Portugal, Trans-Canada Air Lines (later renamed Air Canada), Aer Lingus, VARIG, Cubana de Aviación, Línea Aeropostal Venezolana, Northwest Airlines, and Avianca, the national airline of Colombia.

RecordsEdit

Sleek and powerful, Constellations set many records. On April 17, 1944, the second production C-69, piloted by Howard Hughes and TWA president Jack Frye, flew from Burbank, California, to Washington, D.C., a distance of approximately Template:Convert, in 6 hours and 57 minutes, representing an average speed of Template:Convert. On the return trip, the aircraft stopped at Wright Field in Ohio to give Orville Wright his last flight, more than 40 years after his historic first flight near Kitty Hawk, North Carolina. He commented that the Constellation's wingspan was longer than the distance of his first flight.<ref name=yenne />

On September 29, 1957, a TWA L-1649A flew from Los Angeles to London in 18 hours and 32 minutes—about Template:Convert at Template:Convert.<ref name=Buck>Template:Cite magazine</ref> The L-1649A holds the record for the longest-duration, nonstop passenger flight aboard a piston-powered airliner. On TWA's first London-to-San Francisco flight on October 1–2, 1957, the aircraft stayed aloft for 23 hours and 19 minutes (about Template:Convert at Template:Convert).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}Template:Dead link Longer Range, New Routes.

ObsolescenceEdit

Jet airliners such as the de Havilland Comet, Boeing 707, Douglas DC-8, Convair 880, and Sud Aviation Caravelle rendered the Constellation obsolete. The first routes lost to jets were the long overseas routes, but Constellations continued to fly domestic routes. The last scheduled passenger flight of a Constellation in the contiguous United States was made by a TWA L749 on May 11, 1967, from Philadelphia to Kansas City, Missouri;<ref name=germain>Template:Harvnb</ref> the last scheduled passenger flight in North America was by Western Airlines' N86525 in Alaska, Anchorage to Yakutat to Juneau on 26 November 1968.

Constellations carried freight in later years, and were used on backup sections of Eastern Airlines' shuttle service between New York, Washington, and Boston until 1968. Propeller airliners were used on overnight freight runs into the 1990s, as their low speed was not an impediment. An Eastern Air Lines Connie holds the record for a New York–to–Washington flight from take off to touchdown in just over 30 minutes. The record was set prior to speed restrictions by the Federal Aviation Administration (FAA) below Template:Convert.<ref>"Lockheed Constellation L749 N749NL Comeback." Template:Webarchive World News. Retrieved: February 22, 2011.</ref>

One of the reasons for the elegance of the aircraft was the dolphin-shaped fuselage, a continuously variable profile with no two bulkheads the same shape and a skin formed into compound curves, which was expensive to build. Manufacturers have since favored tube-shaped fuselages in airliner designs, as the cylindrical cross-section design is more resistant to pressurization changes and less expensive to build.

After ending Constellation production, Lockheed chose not to develop a first-generation jetliner, sticking to its military business and production of the turboprop Lockheed L-188 Electra. Lockheed did not build a large passenger aircraft again until its L-1011 Tristar debuted in 1972. While a technological marvel, the L-1011 was a commercial failure, and Lockheed left the commercial airliner business permanently in 1983.Template:Sfn

The initial military versions carried the Lockheed designation of L-049; as World War II came to a close, some were completed as civilian L-049 Constellations followed by the L-149 (L-049 modified to carry more fuel tanks).

The first purpose-built passenger Constellations were the more powerful L-649 and L-749 (which had more fuel in the outer wings),<ref name="Stringfellow and Bowers">Template:Harvnb</ref>Template:Page needed L-849 (an unbuilt model to use the R-3350 turbo-compound engines adopted for the L-1049 ), L-949 (an unbuilt, high-density seating-cum-freighter type, what would come to be called a "combi aircraft").<ref name="Stringfellow and Bowers" />

These were followed by the L-1049 Super Constellation (with longer fuselage), L-1149 (proposal to use Allison turbine engines)<ref name="Stringfellow and Bowers" /> and L-1249 (similar to L-1149, built as R7V-2/YC-121F),<ref name="Stringfellow and Bowers" /> L-1449 (unbuilt proposal for L1049G, stretched Template:Convert, with new wing and turbines)<ref name="Stringfellow and Bowers" /> and L-1549 (unbuilt project to stretch L-1449 Template:Convert).<ref name="Stringfellow and Bowers" />

The final civilian variant was the L-1649 Starliner (all new wing and L1049G fuselage).<ref name="Stringfellow and Bowers" />

Military versions included the C-69 and C-121 for the Army Air Forces/Air Force and the R7O R7V-1 (L-1049B) EC-121 WV-1 (L-749A) WV-2 (L-1049B) (widely known as the Willie Victor) and many variant EC-121 designations for the Navy.<ref>Swanborough, Gordon and Peter M.

After TWA's initial order was filled following World War II, customers rapidly accumulated, with over 800 aircraft built. In military service, the U.S. Navy and Air Force operated the EC-121 Warning Star variant until 1978, nearly 40 years after work on the L-049 began. Cubana de Aviación was the first airline in Latin America to operate Super Constellations.

It was delivered to Air France on November 2, 1953, and was upgraded to a L-1049 G in 1956, serving until August 8, 1967, having totaled 24,284 hours under Air France's colors. After retirement, it was sent to Spain, to be registered EC-BEN, briefly flying humanitarian and medevac missions in Biafra. Aero Fret bought it in 1968, brought it back home to France, registered it as F-BRAD, and operated it on cargo hauls until 1974. When the Constellation landed in Nantes one last time to be scrapped, it was ultimately saved by Mr. Gaborit, who revamped it somewhat by his own modest means to finally park it near the terminal, accessible to visitors for a few years, until the Chamber of Commerce and Industry of the Nantes-Atlantique Airport bought it, to contract the Amicale du Super Constellation to undergo a complete restoration of the aircraft.<ref>"Story of F-BGNJ."

This aircraft was used as a personal transport by General Douglas MacArthur during the Korean War, and later by other Army general officers until 1966, when it was transferred to NASA. Following its permanent retirement in 1970, it was placed on display at a museum at Fort Rucker near Daleville, Alabama. It was acquired by the Planes of Fame Air Museum at Chino, California, in 1992, and overhauled into airworthy condition for a flight to Dothan, Alabama, where it received additional work. After a thorough restoration back to its original configuration with a "VIP interior", it was placed on display at the Planes of Fame secondary location in Valle, Arizona. Then, in 2015, it was sold to Lewis Air Legends, and prepped for a ferry flight to Chino, arriving there on January 14, 2016. On June 20, 2023, the Air Legends Foundation’s Lockheed VC-121A Constellation took off on its first post-restoration flight from Chino Airport.
