Is it illegal for a jet to break the sound barrier?

Within the United States, it is illegal to break the sound barrier. The Federal Aviation Administration regulations are quite clear: “No person may operate a civil aircraft in the United States at a true flight Mach number greater than 1” except in certain, very limited conditions.

How destructive is a sonic boom?

Damage due to a sonic boom is possible in light building components which have a large surface and consist of a material with a low tensile strength. Damage is very rare at overpressures up to about 500 N/m* and can only occur at points at which there were earlier stress concentrations.

Do the Blue Angels break the sound barrier?

The elite F/A-18 Hornet jets used by the Blue Angels are built to fly at Mach 1.8, or nearly twice the speed of sound. But since sonic booms are outlawed over populated areas, the pilots will slow down to a mere 620 mph. Still, said Blue Angels spokesman Lt. Mike Blankenship, “We cannot break the sound barrier.”

Can sonic booms hurt you?

Sonic booms produced by aircraft flying supersonic at altitudes of less than 100 feet, creating between 20 and 144 pounds overpressure, have been experienced by humans without injury. Damage to eardrums can be expected when overpres- sures reach 720 pounds.

Are sonic booms allowed?

The Federal Aviation Administration (FAA) sets regulations relating to United States airspace. 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. Short answer, No.

What would happen if an F-4 made a sonic boom?

The boom was produced by a F-4 flying just above the speed of sound at an altitude of 100 feet. In recent tests, the maximum boom measured during more realistic flight conditions was 21 pounds per square foot. There is a probability that some damage — shattered glass, for example, will result from a sonic boom.

How high can a supersonic jet fly over the ground?

Supersonic operations over land must be conducted above 30,000 feet or, when below 30,000 feet, in specially designated areas approved by Headquarters United States Air Force, Washington, D.C., and the Federal Aviation Administration. The Air Force continues to expand its knowledge of sonic boom.

What damage can a sonic boom Cause?

Sonic booms aren’t just loud; they can also cause physical damage, breaking glass, cracking plaster, and shaking objects off shelves. A boom from a single fighter aircraft in 1966 dislodged tons of rock, crushing archaeological sites in the famous Canyon de Chelly National Monument.

How does the altitude of an aircraft affect the sonic boom?

In general, the greater an aircraft’s altitude, the lower the overpressure on the ground. Greater altitude also increases the boom’s lateral spread, exposing a wider area to the boom. Overpressures in the sonic boom impact area, however, will not be uniform.
