Yay, now hundreds of millions of people can enjoy the continual sound of car doors slamming so the 1% can fly to Aspen and Davos a bit faster.

I don't share jsopr point of view.
I think this is great, this tech is pushing the boundaries of air travel, this is what will enable supersonic travel for the masses, and not just a new Concorde (which could only fly over water because of it's sonic boom).
With maglev trains continuing to get faster, airlines haven't increased their speed in many decades. This will allow a future 797 to be supersonic, anywhere on Earth. Getting people to their destinations faster, who wouldn't want a shorter flight time.

At 17000 meters, 1512kph would be Mach 1.42, because the speed of sound is lower at that altitude than at sea level. Is 1512kph even the cruising speed at that altitude, or is this an arbitrary combination of speeds and altitudes that the craft is capable of at different times?

It's time for a high carbon tax. So high that the 1% become members of the 99% if they continue to pollute the atmosphere and accelerate climate change even quicker than they are now

I remember sitting on the third floor of Norwood Hall in Rolla when MacDonald Douglas flew over supersonic. Got a pretty solid "kick in the pants" from the wood floor! Some people complained of nail popping on drywall.

Instead of developing air travel that is less polluting and more efficient, we're going back in time to get people to their destinations faster with a 75% less boom. Think about that. With all the issues being dealt with in our modern age, is this appropriate? The fact that only a select few will get to enjoy this marvelously unnecessary and retro-future achievement will be the wealthy is so wrong. On top of all that, when these lucky few get to their destinations, they may spend more time in traffic or the train on the last leg of the trip. Just like the Concorde, these jets will need longer runways as well. We're saving six cents to spend half a dozen.

Wow! The reactionary comments here are seriously ridiculous. This is a technology demonstration project and NOBODY knows what commercialization looks like, or even IF it'll be commercialized!

Everyone needs to listen to Aaron Rodgers and R-E-L-A-X.

Seems to me the government is going to use us as test subjects again without our permission.

I'm impressed , that is one sleek aircraft !

Haha, the silly doomsday comments. Please. This is very cool tech. Relax.
