Trump Administration Supports NASA's Quieter Supersonic Plane Design

Trump Backs Supersonic NASA Jet That Will Fly From New York to London in Three Hours [newsweek.com]

A sleek, experimental plane that would quietly crack the speed of sound and transform a trans-Atlantic flight into a three-hour hop received critical backing on Monday under NASA's budget request [nasa.gov] for the fiscal year that starts October 1, 2018. The document signals the Trump administration would like to prioritize the jet, as well as further research into faster-than-sound airplane technology.

The budget request refers to the Low-Boom Flight-Demonstrator, a plane NASA wants in order to bring back supersonic commercial flights by mitigating their most annoying side effect, the loud sonic boom that accompanies them.

That boom has always been the biggest stumbling block for commercial supersonic flight. It is caused by the sheer number of air particles the nose of the plane pushes aside as it flies. Those molecules form a wave of high pressure, like a boat's wake as NASA describes it [nasa.gov], which rolls out like a carpet beneath the airplane.
