The Airline Deregulation Act is a 1978 United States federal law that deregulated the airline industry in the United States, removing U.S. Federal Government control over such areas as fares, routes and market entry of new airlines, introducing a free market in the commercial airline industry and leading to a great increase in the number of flights, a decrease in fares, and an increase in the number of passengers and miles flown.  The Civil Aeronautics Board's powers of regulation were phased out, but the Act did not diminish the regulatory powers of the Federal Aviation Administration (FAA) over all aspects of aviation safety. In 1931, Braniff Airways was serving just five destinations: Braniff Airways Flight 250 crashed near Falls City, Nebraska, on August 6, 1966, en route to Omaha from Kansas City, Missouri.  Thirty-eight passengers and four crew members were killed in the crash, which occurred in a farm field late on a Saturday night.  In-flight structural failure due to extreme turbulence in an avoidable weather hazard was cited as the cause. Paul Revere Braniff (August 30, 1897 – June 15, 1954) was an airline entrepreneur.  Paul, along with his brother Thomas Elmer Braniff, was one of the original founders of Braniff Airways, Inc. d/b/a Braniff International Airways (after 1948). Charles Edmund Beard (November 23, 1900 − July 18, 1982) was the former President of Braniff Airways, Inc. d/b/a Braniff International Airways, from 1954 until 1965.  He was the third president since its inception in 1928, the first person outside the Braniff family to be CEO of the airline.  Beard, along with Braniff Board Chairman Fred Jones (Oklahoma City, Oklahoma Ford dealer magnate), managed the airline conservatively, but recorded record growth and traffic statistics between 1954 and early 1965. Willy Otto Rossel (April 4, 1921 – September 14, 2015) was a Chef de Cuisine or Executive Chef most noted for his extensive work in the preparation of gourmet airline cuisine.  In 1965, he was hired by the progressive Dallas-based Braniff Airways, Inc., to administer the airline's commitment to providing its passengers with the finest food aloft.  Also in 1965, Braniff had begun implementing its revolutionary End of the Plain Plane Campaign, which called for an unprecedented change in the way the airline presented itself to the public.  This campaign not only included a change in the company's look but an upgrade of its inflight cuisine to gourmet status.  Rossel wrote the first manual used for the apprenticeship of American chefs. Braniff Airways, Inc., doing business as Braniff International Airways, from 1948 until 1965, and then Braniff International from 1965 until 1983, was an American airline that operated from 1928 until 1982.  Its routes were primarily in the midwestern and southwestern United States, Mexico, Central America, and South America.  In the late 1970s it expanded to Asia and Europe.  The airline ceased operations in May 1982 because high fuel prices and the Airline Deregulation Act of December 1978 rendered it uncompetitive.  Two later airlines used the Braniff name: the Hyatt Hotels-backed Braniff, Inc. in 1984–89, and Braniff International Airlines, Inc. in 1991–92.  In early 2015, a series of new Braniff companies were incorporated in the State of Oklahoma, for historical purposes and for administration of the Braniff trademarks, copyrights and other intellectual property.  These companies included Braniff Air Lines, Inc., Paul R. Braniff, Inc., Braniff Airways, Inc. and Braniff International Corporation.
