History
In 1947, Howard Hughes redirected the Hughes Aircraft Co.'s efforts from airplanes to helicopters. The effort began in earnest in 1948, when helicopter manufacturer Kellett Autogiro Corporation sold their latest design to Hughes for production. The XH-17 "Sky Crane" first flew in October 1952, but was commercially unsuccessful. In 1955 the compnay began building light helicopters when Howard Hughes split the helicopter production unit from the Hughes Aircraft Co., and reconstituted it with the Hughes Tool Co. as the Hughes Tool Co. Aircraft Division, with a focus on the production of light helicopters.
The Hughes Model 269 was the first successful helicopter design. Built in 1956, and entering production in 1957, it served to capture a large portion of the commercial market for Hughes. It would eventually become part of the Army inventory as a primary trainer (TH-55 Osage). In May 1965, the company won the contract for a new observation helicopter for the U.S. Army, and produced the OH-6 Cayuse (Hughes Model 369). The OH-6 was later developed into the civilian Model 500, variants of which remain in production to this day.
In 1972, Hughes sold the tool division of Hughes Tool Company, and reconsolidated his remaining holdings as the Summa Corporation, which included Hughes' property and other businesses. The Aircraft Division became the Hughes Helicopter Division, Summa Corp. That same year, the US Army issued a request for proposals (RFP) for an Advanced Attack Helicopter (AAH). From an initial list of 5 manufacturers Hughes Aircraft's Toolco Aircraft Division (later Hughes Helicopters) and Bell were selected as finalists. In 1975, Hughes' Model 77/YAH-64 was selected over Bell's YAH-63. First flight of a development prototype occurred in 1977. Also in 1975, Hughes engineers at began concept development work of NOTAR.

Famous quotes containing the word history:
“Certainly there is not the fight recorded in Concord history, at least, if in the history of America, that will bear a moment’s comparison with this, whether for the numbers engaged in it, or for the patriotism and heroism displayed.”
—Henry David Thoreau (1817–1862)
“Only the history of free peoples is worth our attention; the history of men under a despotism is merely a collection of anecdotes.”
—Sébastien-Roch Nicolas De Chamfort (1741–1794)
“He wrote in prison, not a History of the World, like Raleigh, but an American book which I think will live longer than that. I do not know of such words, uttered under such circumstances, and so copiously withal, in Roman or English or any history.”
—Henry David Thoreau (1817–1862)
