Boeing's 2707 supersonic transport was designed to fly at Mach 2.7 — 2,071 miles per hour — carrying up to 277 passengers, more than triple the capacity of the Anglo-French Concorde. Powered by four General Electric GE4 turbojets, the largest straight turbojet engines ever built, two prototypes were under construction in Seattle when Congress killed the program in 1971 by a single Senate vote. Boeing laid off more than 60,000 workers, pivoted to the subsonic 747, and 55 years later no American supersonic airliner has ever entered service.
