What happens when an airplane is flying faster than the speed of sound?
What happens when an airplane is flying faster than the speed of sound? As an aircraft flies at supersonic speeds it is continually generating shock waves, dropping sonic boom along its flight path, similar to someone dropping objects from a moving vehicle. From the perspective of the aircraft, the boom appears to be swept backwards as it travels away from the aircraft.
Did Concorde break the sound barrier?
At their cruising speeds, the innovative Concordes flew well over the sound barrier at 1,350 miles an hour, cutting air travel time by more than half. The flights were the culmination of a 12-year effort that pitted English and French engineers against their counterparts in the USSR.
Are jets allowed to break the sound barrier?
Penney said they are allowed to break the sound barrier in a limited number of scenarios: over the ocean or on a training range where it won't disrupt everyday life, or in an emergency with a superior's approval.

At what speed does a jet break the sound barrier?
For example, the speed of sound at 30,000 feet is about 670 miles per hour, but an aircraft must travel at least 750 miles per hour (Mach 1.12, where Mach 1 equals the speed of sound) for a boom to be heard on the ground.
Can civilian pilots break the sound barrier?
On March 10, 1948, Hoover became the first civilian and only the second pilot ever to break the sound barrier. Eight years earlier, Hoover had accepted a position with the National Advisory Committee for Aeronautics (NACA) in Hampton, VA, where he flew more than 100 different aircraft.
Has a 747 ever broken the sound barrier?
Aircraft are put through extreme testing during their certification, but such limits are never intended to be actually faced. The 747 -100, for instance, was tested up to Mach 0.99, almost breaking the sound barrier. Other 747s, such as Air Force One, have approached the sound barrier but never crossed it.
Do pilots need permission to go supersonic?
A sonic boom is a loud noise that people on the ground can hear when an aircraft, for example, breaks the sound barrier by traveling faster than the speed of sound. Supersonic flight is banned over land in the US without special government authorization because of the inconvenient noises and tremors it can produce.
