Known as the Low-Boom Flight Demonstrator (LBFD), this X-plane is scheduled to make its first test flight as early as 2021 and "would open a new market for U.S. companies to build faster commercial airliners, creating jobs and cutting cross-country flight times in half," the White House budget request states.
The goal of supersonic aircraft like LBFD is to make commercial airplanes that can fly faster than the speed of sound without generating a loud and obnoxious sonic boom, an ear-splitting noise associated with shock waves generated by an aircraft as it breaks the sound barrier
"Future supersonic aircraft seeking to achieve a low-boom, such as NASA's LBFD, will rely on a swept wing design in order to fly at supersonic speeds without producing a loud sonic boom," NASA officials said. "The swept wing design generally produces crossflow, which is a name for air flow disturbances that runs along the span of the wing, resulting in turbulent flow, increased drag and ultimately higher fuel consumption."
The agency has already been testing preliminary designs of the LBFD X-plane. Last summer, a scale model known as the Quiet Supersonic Transport (QueSST) aircraft was put to the test in a supersonic wind tunnel at NASA's Glenn Research Center in Cleveland. With the financial support allotted by the 2019 budget request, the agency would be able to start building the full-scale LBFD with the goal of beginning flight tests in 2021.
"This budget maintains a robust investment of $633.9 million to improve air traffic management, make progress integrating unmanned systems into the airspace, and fund an experimental supersonic airplane and increase hypersonics research," NASA Acting Administrator Robert Lightfoot said during the annual State of NASA speech on Monday

The sonic boom will be transformed into a sonic thud.
Phooey!
I wasn’t objecting to anything. I was noting that the airlines have posted plans to make people stand up while flying, so as to get more passenger on planes. They may sell the idea with a two hour flight to Europe or Asia. Their argument may be, “You can stand for two hours can’t you.”
Is this the one that they plan to stack us like cordwood in for passenger service?
is "NO".

“Post that to the buffoons who came up with the silly, irrelevant objections.”
You wanna take this outside? ;-)
Come on Regulator,
You mean NASA’s primary mission isn’t Mooselimb outreach?
The “magic negro”, sure isn’t a happy camper about this. Just what the hell is NASA’s mission anyway?
For that matter, What the hell is the IRS, INS, Justice dept, Cia, Fbi. and every other DAMNED federal bub mint agency there for?
Oh yeah, Comiong together and getting rid of the legally elected president of the U.S.A.
Cam you say, mookabookin banana republic?
Whole lot of folks need serious prison time or the WHOLE federal gub mint is hourse shit.
Think - virtual windows
They have to be real, and unobtruded by a wing.
