These problems were well understood within the industry; the IATA released a set of "design imperatives" for an SST that were essentially impossible to meetthe release was a warning to promoters of the SST within the industry. The committee proposed a variety of alternative designs, all under the name Model 733. [18], By this point, the opposition to the project was becoming increasingly vocal. Acounterattack was organized under the banner of the "National Committee for an American SST", which urged supporters to send in $1 to keep the program alive.

Labor unions also supported the SST project, worried that the winding down of both the Vietnam War and Apollo program would lead to mass unemployment in the aerospace sector. [35], The Museum of Flight in Seattle parks a British Airways Concorde a few blocks from the building where the original 2707 mockup was housed in Seattle. A promotional film claimed that airlines would soon pay back the federal investment in the project, and it was projected that SSTs would dominate the skies with subsonic jumbo jets (such as Boeing's 747) being only a passing intermediate fad. From the start, the airline industry had noted that the economics of the design were questionable, concerns that were only partially addressed during development. Lockheed's L-2000 was judged simpler to produce and less risky, but its performance was slightly lower and its noise levels slightly higher. Lockheed's entry, designated CL-823, was essentially an enlarged Concorde. The name was inspired by the newly won SST contract.[40]. The final-configuration Boeing 2707 mockup was sold to a museum and displayed at the SST Aviation Exhibit Center in Kissimmee, Florida, from 1973 to 1981. [citation needed] By the 1980s, glass cockpits became standard on all large commercial jets and by the 2000s, most light aircraft were equipped with them. McNamara was highly skeptical of the SST project and savaged Halaby's predictions; he was also afraid the project might be turned over to the DoD and was careful to press for further studies. They felt that there was no way to build a transatlantic design with that performance in time to catch the Concorde's introduction, abandoning the trans-Atlantic market to the Europeans. Flexing of the fuselage (it would have been the longest ever built) threatened to make control difficult. Original model by Kazunori Ito, updated for FSX by Michael Pook. After winning a competition for a government-funded contract to build an American SST, Boeing began development at its facilities in Seattle, Washington. Compared to the other designs, the rounded nose profile and more cylindrical cross-section gave the NAC-60 a decidedly more conventional look than the other entries. In 1983, the building, complete with SST, was purchased by the Faith World church. [34], Nevertheless, the SST race has had several lasting effects on the industry as a whole. It was one of the earliest wide-body aircraft designs, with 2-3-2 row seating arrangement at its widest section[14] in a fuselage that was considerably wider than aircraft then in service. The use of high-lift devices on the leading edge of the wing lowered the landing angles to the point where the "drooping nose" was not required, and a more conventional rounded design was used. Considerable wind tunnel testing of the various models was carried out at NASA's Langley Research Center. The only major design difference was the use of individual pods for the engines, rather than pairs. Production aircraft could start being built in early 1969, with the flight testing in late 1972 and certification by mid-1974.[14]. Windows were only 6 inches due to the high altitudes the aircraft flew at maximizing the pressure on them, but the internal pane was 12" to give an illusion of size. In October 1968, the company was finally forced to abandon the variable geometry wing. [29] The two prototypes were never completed. The design emerged as a large aircraft with seating for 250 to 300 passengers and cruise speeds of approximately Mach 3. [28], At the time, there were 115 unfilled orders by 25 airlines, while Concorde had 74 orders from 16 customers. [19] Later, an additional threat to the ozone was found in the exhaust's nitrogen oxides, a threat that was later validated by MIT. [citation needed], Its Soviet counterpart, the Tupolev Tu-144, was less successful, operating for only 55 passenger flights before being permanently grounded for various reasons. In the main 247-seat tourist-class cabin, the entertainment system consisted of retractable televisions placed between every sixth row in the overhead storage. After a lengthy review the Boeing design was announced as the winner on January 1, 1967. [6], In spite of vocal opponents, questions about the technical requirements, and extremely negative reports about its economic viability, the SST project gathered strong backing from industry and the FAA. [13], The North American NAC-60 was essentially a scaled-up B-70 with a less tapered fuselage and new compound-delta wing. [31], With the ending of the 2707 project, the entire SST field in the U.S. was moribund for some time. Environmentalists were the most influential group, voicing concerns about possible depletion of the ozone layer due to the high altitude flights, and about noise at airports, as well as from sonic booms.[19].
