Why can't jets break the sound barrier at airshows?
Why can't jets break the sound barrier at airshows? Flying so close to the ground, the air is denser and creates more friction and drag – and, anyway, pilots are banned from breaking the sound barrier over land. “You can do it over the sea,” he says, “but you can't do it over the land.
How many mph is supersonic?
Supersonic speed is the speed of an object that is faster than the speed of sound, measured at about 768 miles per hour at sea level. Supersonic speed is one of the four “regimes of flight” (subsonic, transonic, supersonic, hypersonic).
How fast do jets fly at airshows?
The highest speed flown during an air show is 700 mph (just under Mach 1) and the lowest speed, is 126 mph (110 knots) during Section High Alpha with the new Super Hornet (about 115 knots with the old Legacy Hornet).
Why we don t hear sonic booms anymore?
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.
Why is breaking the sound barrier illegal?
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.

Can a pilot feel a sonic boom?
And the jet pilots don't feel a sonic boom from the cockpit, just as passengers on a boat don't feel the effects of the wake behind them, she added.
