Boeing reveals "Hypersonic Flight Concept"
Chicago - Flying five times faster than the sound speed might sound like a distant future story, but according to Boeing, the hypersonic flight can be a reality in twenty to thirty years. The American aircraft manufacturer presented its first-ever concept for a hypersonic passenger plane for military or commercial customers, which could cross Atlantic or Pacific ocean in two hours.

It would be greatness if this ever comes to fruition. I grew up in the 60's and remember when Congress cancelled funding for the Boeing SST. I was pretty bummed about it as a kid. I believe that materials technology and tech in general has progressed to the point where this is actually viable. Having endured many many international flights of 12-16 hours, cutting travel times by half, third or even a quarter would be a God-send.
Hypersonic ? two hours to cross the ocean ? this is an accomplishment.
Here are a couple practical issues.
1st. sonic boom. Unless Boeing's engineers can figure out a way to violate the laws of physics. such an aircraft would not be able to fly supersonic over any populated land mass.
second.Presuming this aircraft would fly at altitudes exceeding 60k feet, there are certain stresses on materials that would have be addressed. I read quite a bit about the development of the SR-71 Blackbird.

Perhaps you're referencing your assumption of physics, not the laws of physics.

Sonic booms can be made over the US and has been done for years with the SR-71. One cannot forget the record setting flight from LA to DC in 1 hour and 8 minutes at 2200MPH. That was at about 80,000 feet.

It's illegal for civilians. The SR-71 is far from the most recent supersonic flight over the US. There have been plenty, but they all wear uniforms.
i remember this Boeing concept about 20 years ago.... something like 15 to 17,000 mph speed...
New York to Sydney in about an hour or an hour and one half....
.... you could take off today in Sydney and arrive 'yesterday' in NYC....
what happens with the sonic booms? will not the environmentalists have another issue???
interesting ...when SST was running between NYC and London..if you were on a NJ Beach around
Point Pleasant at about 3PM each day..you could hear the sonic boom when the SST started it's
approach to NYC....you could set your clock by it.... love to fly on this new item if I am still
alive by then...take care all
