On October 1, 1962, Trans world Airlines (TWA) inaugurated the first fully automatic doppler radar system of navigation on scheduled transatlantic flights. The New York to London flight held the honour of being the first transatlantic flight to operate without a professional navigator as part of the flight crew.
Trans International Airlines (TIA) was a non-scheduled Charter Airlines that operated regular charter flights between the US and Europe and saw service briefly in the Vietnam War. The airline, acquired by Entertainment and travel mogul Kirk Kerkorian, was riding the postwar boom in commercial aviation as a sea of former air force pilots and demilitarised aircraft flooded the civilian industry. It held the honour of being the world’s largest charter airline with the acquisition of Saturn Airways in December 1979.
During the administration of Calvin Coolidge, the US government looked to Pan Am as an extension of US foreign policy which would allow economic expansion into Latin America and the Caribbean. The US government “awarded Pan Am every foreign airmail route for with bids were invited”. The success of Pan Am was largely attributed to the diplomatic genius of the company’s founder and visionary, Juan Trippe, and the Foreign Mail Act. This Act, passed with the purpose of regulating the international mail service, stipulated that only airlines capable of operating with scale while upholding the dignity of the United States would be allowed to carry mail. Not only that, the Act stated that contracts would only be granted to companies that were given invitations by Latin American Countries. Trippe maintained good relations with leaders of these countries thereby securing air routes.
