During the 1900s in their garage, brothers Malcolm and Allan Loughead started the Alco Hydro-Aeroplane Co. After failure it was succeeded by Loughead Aircraft Mfg., Co., and later Lockheed Aircraft Company. Unique single-shell, wooden monocoque construction put the Vega and cabin planes ahead of their competitors' fabric-covered biplanes. Lockheed's twin-engined transports led to Hudson and Ventura bombers and the twin-engined fighter, XP-38 Lightening. WWII saw Lockheed produce 19,077 aircraft. Then came the first jet fighter, P-80, and the U-2 and SR-71 spy planes. The F-104 Starfighter and F-117A stealth fighter followed. In 1961 reorganization brought about Lockheed-Georgia Co. In 1977 Lockheed Corporation was formed.
