Supersonic airplanes are old news. But supersonic airplanes that can fly nine times the speed of sound? That’s something else.
Texas-based company Venus Aerospace is designing a passenger plane called Stargazer that’s capable of flying at Mach 9, or approximately 6,900 miles per hour — which means you’d be able to fly from New York to Sydney in less than 90 minutes. By comparison, the Concorde, which was the only supersonic passenger plane ever to fly commercially, flew at about Mach 2, or more than 1,500 miles per hour.
