This unique book reproduces important NASA, FAA, and other government documents, reports, and studies about the history and current state of supersonic passenger aircraft and SST travel. Updated through June 2019 with the latest information, there is extensive technical coverage of the ongoing NASA Low Boom Flight Demonstrator X-59 QueSST (LBFD) Project, a new X-plane that will test its quiet supersonic technologies by flying over communities in the United States. X-59 is designed so that when flying supersonic, people on the ground will hear nothing more than a quiet sonic thump - if anything at all.Contents: NASA Low Boom Flight Demonstrator X-59 QueSST (LBFD) Project * Part One: Overview * Part Two: Budget Presentation * Part Three: X-59 Life Support and Crew Escape System Design Challenges * Part 4: Zoom without the Boom * Part 5: Human Response to Sonic Booms * Part 6: Supersonic Passenger Flights / 2018 Research Report * Part 7: FAA Fact Sheet - Supersonic Flight * Part 8: What Happened to the American SST?Four decades have passed since the first trans-oceanic supersonic passenger flight took off from London Heathrow Airport in 1976. Subsequently, more than 2.5 million passengers flew supersonically until British Airways and Air France took the Concorde out of service in 2003. Although no supersonic passenger aircraft have flown since then, aviation enthusiasts, aircraft and parts manufacturers, airlines, and some Members of Congress have expressed interest in restarting supersonic air travel. Several U.S. startup companies are now developing supersonic commercial and business jets. The major issues affecting the introduction of supersonic aircraft appear to remain the same as in the Concorde era-how to translate technological advances into commercial ventures that are economically viable and acceptable to regulators and the public. Gaining international consensus and approvals to fly supersonically over other countries besides the United States may be a criti
