The hypersonic passenger plane could, in theory, fly as fast as Mach 5, or just under 3,900 miles per hour. That would allow the plane to carry passengers between Los Angeles and Tokyo in roughly three hours. A flight from New York to London could be as quick as two hours. Right now, those flights take about 11 hours and 7 hours, respectively.
Boeing CEO Dennis Muilenburg is pushing the aerospace giant to explore the potential of ultra-fast passenger planes.
"I think in the next decade or two you're going to see them become a reality," Muilenburg told CNBC at the Paris Air Show last year. “We see future innovations where you could connect around the world in about two hours.”
How will Boeing and other aerospace companies build passenger planes that can safely fly between far-flung locations in just a few hours? The key will be the development of lightweight materials for the fuselage and new engines that will propel the jets at greater speeds. All of that will take years to be designed and tested.
Then there is the question of cost. How willing is Boeing to potentially spend billions of dollars over the next 20 to 30 years to build a hypersonic passenger plane? If the jet is built, will the costs be low enough to make it a profitable plane for airlines to fly on a regular basis?

How can Boeing afford it?
Get government support. A hypersonic object with the mass of an airliner is an awesome weapon as well as prompt transport. Russia has invested heavily in this area, or at least bragged about it. I wouldn’t be surprised if the US had some projects in this area already, as well.
OK, have been seeing renderings of these things all my life....
Build one already!!
I strongly suspect that is what's behind this.
It sometimes seems some new take on the old Boeing SST is trotted out every few years.
Building one isn’t the problem.
Selling ten is.
Boom Supersonic already has more than 74 orders for it’s futuristic SST.
Exactly. My daughter could produce a nice drawing of such a thing, but it would be no nearer reality than her drawings of space-travelling dragons.
When they have a failure its gonna be that much more fast and spectacular.
Space-traveling dragons? Now that’s what I’m talkin’ bout. You need to have her contact the new Space Force. Only thing better might be space-traveling Ligers.
She sounds like a Freeper in training.
I don’t know where this screwball idea came from but the proposed aircraft certainly won’t be hypersonic at ground level.
Communication that involves typing is too old-fashioned for today’s youth.
Concorde is a British-French turbojet-powered supersonic passenger airliner that was operated from 1976 until 2003. It had a maximum speed over twice the speed of sound at Mach 2.04 (1,354 mph or 2,180 km/h at cruise altitude), with seating for 92 to 128 passengers.
“Building one isn’t the problem.
Selling ten is.”
Yeh, the technology to build a large supersonic passenger plane has been in place for awhile now. The trick is building one that can operate at a profit. That technology has yet to prove itself to exist....
Just make sure there aren’t any pieces of metal on the runway at takeoff.
Forget that. We should build a high-speed train to Japan. It can go under or over the ocean, and the governor of California can head up the project, as he has valuable experience with these things.
I think Spacex will beat them with a pure rocket solution. They have already demonstrated the technology.
Ping.
