How would you like to fly from New York to London and an hour? Or how about London to Tokyo in two hours? Some day you might be able to if the ZEHST plane gets off the ground.
A new hypersonic jet, dubbed ZEHST for Zero Emission Hypersonic Transportation, was revealed at the Paris Air Show on Sunday. The plane, which debuted in mockup form, will reach speeds of 3,125 mph, or roughly four times the speed of sound (Mach 4), the Daily Mail reports.
