NASA's incredible X-plane that is shaped to muffle the sound of its sonic boom has been cleared for assembly by a management review ahead of test flights in 2021.
Dubbed the 'son of Concorde' after the Mach 2 airliner, the X-59 Quiet SuperSonic Technology (QueSST) is NASA's first large experimental plane in three decades.
The X-59 will cruise at Mach 1.42 (1,090 mph/1,754 km/h) and is designed for supersonic flight while preventing its sonic boom from being heard on the ground.
If successful, the craft could one day travel from London to New York in just over three hours, while transcending objections to supersonic air travel over land.

Uh, maybe “How Dare YOU!” Between gulps from her throw away water bottle.
Thanks for including a pix.
**Looks like a longnose gar with wings.**
Silly you. Who said anything about passengers sitting upright. Everyone lies down and is slid in like loading a 16”er on the USS Missouri. No need for all those windows. Each will be given googul glasses to see what the pilot sees.
Oh yeah....., and everyone wears depends for the trip.
Why is NASA blowing money on quieter supersonic flight, when it is cutting back on vital Muslim outreach?

Always remember it’s not a good idea to transfer
from a moving vehicle or from a vast difference in
altitude...
especially at Mach 1.5................
They can’t get the dope for the wings any more.
It's certainly got a Thunderbirds (TV show) vibe to it.
I’m not an aerospace guy but IIRC the angle of the mach lines increases with speed until you hit the speed of sound at which point the angle stays constant. So you can’t avoid an audible boom on the ground by narrowing the mach cone.
I’m guessing they’re softening the boom by spreading out the energy of the pressure wave. The long pointy nose displaces air in a relatively gradual way compared to a blunter nose. The result is a waveform with more duration but less intensity which is perceived by the ear as softer.
The Concorde had 4 engines. This prototype seems to have one, though I assume the final plane will need more than one.

What doomed the Concord was that it was expensive, and it only cut the NY-London flight time from 7 hours to 3. Adding in the time to get to the airport, go through security, board, get off at the other end, get your luggage, get through customs — transatlantic travel remained an all-day affair, and cutting 3-4 hours off was not worth spending tremendously more for.
Now, if Concord had the fuel capacity for trans-Pacific flight, and was able to cut flight times to Asia or Australia from 14 hours to 7, then lots of people would have been interested. But it didn’t have the range.
*ping*
Yeah, any ****ing day now. Musk will be shooting passengers across the Pacific in 30 minutes before this thing has a successful flight test. And I'm not an optimist when it comes to Musk's plan. Thanks fieldmarshaldj.
Does NASA have their handicapped transgendered persons of color pilots lined up ? If not, shut it down ! Racists !
