They'll probably never let humans travel by air at hypersonic speeds, its far to dangerous.

They'll simply use Evacuated tube maglev(Elon Musk's HYPERLOOP) for long distances, same hypersonic speed.

Looking forward to breakfast in San Fransisco, Lunch in LA, and Dinner in Washinton DC.



Haven't they let humans travel by air at hypersonic speeds already?

http://en.wikipedia.org/wiki/Concorde


Concorde has a max speed of just over Mach 2.0. Hypersonic means Mach 5.0 or higher. The rocket-powered X-15 max speed was 6.7, and of course the Space Shuttle also went faster than Mach 5.0, so yes, humans have already flown at hypersonic speeds.


HYPERsonic means Mach 5.0 or higher

Whoops.


Why is it far too dangerous?
