“Sonic boom” is also misleading because high-speed airplanes create two distinct sources of constant noise. “As the aircraft moves along its path,” Wild said, “all underneath the path of the aircraft you’ll get this sound - this big rumble following the aircraft.” If you’re on the ground when the shock wave produced by a faster-than-sound aircraft passes, you hear it. If you’re on the water when the wake passes, you feel it. The air disrupted by supersonic travel is akin to the wake behind a speed boat. What happens is, as the aircraft is moving faster than sound, that shock wave moves with that aircraft.” “But it’s not just when that aircraft passes through the sound barrier. “People tend to think of the noise as being when the aircraft is breaking the sound barrier,” Jim Wild, a professor of space physics at Lancaster University, told the BBC in 2012. Overture’s predecessor, the British Airways- and Air France-operated Concorde SST, could only fly transatlantic flights where its thunderous din was inaudible to populous areas. With few exceptions, the disruptive noise is prohibited by law over the United States and near its coastal regions. Supersonic jet maker negotiating with NC to build a manufacturing plant in Greensboro Questions about Overture, Boom Supersonic’s new version of the Concorde? We have answers Who is Boom Supersonic? Background on the airplane maker that might be coming to PTI What is a sonic boom? Think in terms of rolling thunderīoom Supersonic, an airplane maker partnering with United Airlines and others to revive supersonic passenger travel, is negotiating space for a major manufacturing facility at Greensboro’s Piedmont Triad International Airport, where it would build its Overture jetliner, a 205-foot passenger plane capable of traveling about 1,300 mph.Īt such speeds - well beyond the speed of sound - aircraft make a deafening roar known as a sonic boom.
