A Brief Historical Overview of Boeing's Attempt to Create a Hypersonic Passenger Aircraft:
On November 29, 1962, England and France signed an agreement to jointly work on the project of a supersonic passenger aircraft, the "Concorde." This idea greatly appealed to the head of Pan American World Airways, Juan Trippe. He ordered six aircraft from the French and British for tens of millions of dollars and then deliberately leaked this news to the American press. President John Kennedy was very displeased. The next day, on June 25, 1963, he announced that the United States would undertake an important new program in civil aviation—the creation of its own supersonic passenger aircraft, the SST (Supersonic Transport).
Boeing, Lockheed Corporation, and North American entered the competition for the government contract to build the supersonic aircraft. Boeing won, developing a revolutionary design. The full-scale model, designated the Boeing 2707, became the focus of attention for all aviation industry representatives. It was 97 meters long, had four engines, could carry 300 passengers, and had a speed of Mach 2.7. However, even optimistic estimates suggested that this aircraft would not be operational for at least ten years.
Juan Trippe did not want to wait. Thus, he came up with the idea of obtaining a so-called replacement aircraft in the meantime. He approached Boeing with the idea of developing the largest passenger aircraft of that time—the Boeing 747. At that time, the largest airliner was the DC-8, which could accommodate about 250 people. The new 747 was to hold 400 passengers. Juan Trippe signed a contract with Boeing for 25 747 aircraft. The directors of other airlines were horrified. How could such a large aircraft ever be filled? But Juan Trippe was confident that with such an aircraft, Pan American could reduce transportation costs. Boeing's management promised to deliver the first airliner within four years. The task of realizing these plans fell to the engineer Joe Sutter.
In 1971, the U.S. Senate terminated funding for the supersonic passenger aircraft project. The aircraft was becoming too expensive, and the costs were skyrocketing. The project was closed, and the model was dismantled. Its nose section is preserved at the restoration center of the "Museum of Flight" in Everett.
