NASA's Quieter Supersonic Jet

NASA has released the results of its engine performance tests on the new X-59 research jet, which is not built for space, but has the potential to change air travel down here on earth. You might not know this, but civilian planes that travel faster than the speed of sound were banned in the US in 1973 because their sonic booms could shatter glass and frightened the daylights out of people on the ground. And that's why passenger jets cannot travel at 800 miles per hour. Even in Europe, the Concorde was phased out for being too expensive to operate.

But NASA intends to upgrade commercial flight with the X-59, bringing back airline travel at faster than the speed of sound. The X-59 not only has a quieter jet engine, it is mounted on top of the plane to reduce shock waves going to the ground. It also sports a slim fuselage that can slice through the air, again reducing shock waves. They would have done much better getting their point across if they showed us the jet with natural sound.
