Bear with me, this was a school project and I had to dumb it down
The dream of flight, Man’s dream of flying among the birds. But, for some, the dream was the go faster than the speed of sound. This dream was made possible with a plane called the Concorde. The Concorde was a type of Supersonic Transport (Referred to as SSTs) But after the Crash of Air France flight 4590, and the attacks of September 11th, 2001, Supersonic travel was halted. Now, with more advanced technology, Supersonic Transports are Feasible for the near future of Aviation.
First off, Looking back at the first viable SST ideas. The Boeing 2707 Design, The Aeropostale/BAC Concorde, and the Tupolev TU-244 are all SSTs that were either designed or actually flew. But, the only one of these 3 that actually flew commercially and was well known was the Concorde. Coming in with the max speed of Mach 2.02, it could fly at 55 to 60,000 feet and it could make the Transatlantic flight from New York JFK-London Heathrow in just under 3 hours.That’s about as long as a car ride from Philly to Washington, DC. Today that flight takes about 5-7 hours, about the same time from Philly to Concord, New Hampshire. Sadly, due to fears after the 2000 Air France Concorde crash, the Concorde was retired and never again did man fly faster than the speed of sound on a passenger aircraft.
The Dream of Supersonic Travel was toned back, but not defeated. A startup called Boom has relit the fire of SSTs. The Boom Overture concept is a SST design which takes the failures of the Concorde, and makes it better. The Overture can do Sydney to San Francisco in just under 6 hours, where it takes 14 now. Now some people may say that Supersonic Travel has too many risks for it to be reliable for passenger travel. While this may be true, it will be with better technology, and better safety procedures than the 90s and the Concorde. You could get a donor heart to a dying patient in a quicker time.
The cabin noise on the Concorde was one of the main problem due to the fact that it had to use a full afterburner to maintain Mach or supersonic speeds. But the main problem with supersonic air travel was the noise on the ground. For context, when you reach Mach 1.1 or higher you “break” the sound barrier ( See above). While you are doing this, the aircraft produces a sonic boom. This was the problem with the supersonics, as they couldn’t fly low over land because the noise would be unbearable. So they couldn’t fly “short” distances fast because it needed to maintain a 45,000 to 60,000 ft altitude to reach supersonic speed. The Boom Overture will use new Symphony engines that take the sonic boom from sounding like a Cannon firing to a car door slamming. These Symphony engines are still in development, but it will revolutionize travel as we know it.
In conclusion, I believe that the Overture is the future of aviation. Imagine going to an afternoon business meeting in London and landing in New York in time to tuck your children into bed (or of your like me your dog 
). This will revolutionize travel as we know it.
