Own a piece of history. This is a briefing book used by Boeing to brief on the Boeing 733 Supersonic Transport (SST) This was a conceptual aircraft design proposed by Boeing in the 1960s as the United States' answer to supersonic airliners like the Concorde (from Britain and France) and the Tupolev Tu-144 (from the Soviet Union). It was part of a larger U.S. government initiative to develop a commercial supersonic transport through funding and competition.

Key Facts:
Designation: Boeing 2707 or Boeing 733 SST (sometimes both terms are used; "733" refers to a specific design iteration)
Era: 1960s-early 1970s

Goal: To create a supersonic passenger aircraft capable of flying faster and carrying more passengers than Concorde
Top Speed (Planned): Mach 2.7 (about 1,800 mph or 2,900 km/h)
Range (Planned): Around 4,000-5,000 miles
Passenger Capacity (Planned): Initially designed to carry around 250-300 passengers, much larger than Concorde's ~100

Features: Swing-wing (variable geometry) design was initially proposed to allow better performance at both subsonic and supersonic speeds. Later models switched to a fixed delta wing due to engineering challenges. Sleek, futuristic design that captured public imagination

What Happened: Boeing won the U.S. SST competition against Lockheed in 1966.
Despite early enthusiasm, the program faced increasing technical challenges, environmental concerns (especially sonic booms and ozone depletion), and cost overruns.
Public opposition and Congress's reluctance to fund it led to the program's cancellation in 1971 before any prototype ever flew. Only a mockup and some test structures were built.

Legacy: The Boeing SST remains a symbol of ambitious 20th-century aviation dreams.
The Concorde went on to become the only successful commercial SST (along with the short-lived Tu-144). Boeing pivoted to developing more efficient subsonic wide-body jets like the 747, which became a massive commercial success.
