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.

Current rules prohibit commercial airplanes from flying at supersonic speeds over land because of the noise levels associated with sonic booms and the negative impacts to humans and animals.
Fifty years ago, the federal government banned all civilian supersonic flights over land. The rule prohibits non-military aircraft from flying faster than sound so their resulting sonic booms won't startle the public below or concern them about potential property damage.
In 1973, the Federal Aviation Administration banned supersonic commercial flights over land because of sonic booms — a prohibition that remains in effect today.
The power, or volume, of the shock wave depends on the quantity of air that is being accelerated, and thus the size and shape of the aircraft. As the aircraft increases speed the shock cone gets tighter around the craft and becomes weaker to the point that at very high speeds and altitudes no boom is heard.
Spike Aerospace, founded in 2013 Max Kachoria of NASA, built an 18-passenger supersonic jet with low-sonic boom, fuel efficiency, speeds up to 1,100 mph, and flight times slashed in half. Their current model is the S-512 which can get passengers to cities in a moment's notice: NYC to London: 3 hours.
