Passengers could break the sound barrier again as technology delivers faster but quieter jets
Supersonics are back. Around the world, aerospace companies and organisations, including Nasa, are developing the technology that will allow passengers once again to fly at faster than the speed of sound. The first of this new breed of aircraft could be flying early in the 2020s.
It was way back in 2003 that Concorde was retired. The airliner entered service in 1976 but was hobbled by complaints that it was too loud. As a result, it could only break the sound barrier when flying over the ocean. This restricted its operation and turned it into a niche aircraft operated only by British Airways and Air France on transatlantic flights.
“The technology simply did not exist to create a new generation of practical and efficient supersonic airliners,” says Doug Nichols, CEO of Aerion, an aviation company in the vanguard of the revival. Now, however, technology has advanced and companies smell profits.

Lockheed Martin N+2.
This is a conceptual design for an 80-seater airliner. Its shape reduces the noise of the sonic boom from a sharp crack to a distant thump, making it acceptable for use over land. A model has been tested in wind tunnel trials and software has been developed to predict the volume of the sonic boom from the shape of the design. “The tools we’ve put in place really open up future opportunities,” says Michael Buonanno, Lockheed Martin manager of the Nasa N+2 programme.

3 Hrs 45 mins estimated:
Speed of sound is 768 Mph
Your commercial aircraft speed is 575 Mph
575/768 = 0.75
0.75 x 5 hrs
=
3 Hrs 45 mins
Take into account that the plane will be travelling at above the speed of sound not at the speed of sound then add on the time taken to reach that speed.
Like to say it would take 3 Hrs 15 mins, but with no precise speed stated I made a conservative estimate.
So:
3 Hrs 15 mins - 3 Hrs 45 mins estimated.

The concord2 speed could be Mach 4.5...

Hardly an improvement, considering that it's going to be a pricey ticket

Heard or read somewhere that Concorde ('76- '03) may fly again.
Here it is.

According to that article the Concorde travelled at "almost twice the speed of sound".
So, going back to Plained's question:

becomes
1 Hr 23 mins
Pretty neat going from 5 hours to 1 hour 23 mins!

I wanna get one of those digital picture frames and just put
on it running on an infinite loop. Put it in the bathroom or something.
