      • In 1973, the Federal Aviation Administration, or FAA, made a new rule that commercial airplanes couldn’t fly at supersonic speeds over land in the United States because of sonic booms. Some companies still designed and built supersonic jets, but these planes could only fly at supersonic speeds over the ocean.

  2. Oct 15, 2020 · But despite Boom's stated intention to fly supersonic over the sea and Aerion's belief that Mach 1.4 flights can be tolerated overland, US regulators have yet to lift a ban on civil...

  3. Jun 4, 2021 · The boom limits where the planes can fly. Typically they must lower their speed until they are out over the ocean, away from citizens who may be disturbed by the loud bang.

  4. Overture is intended to carry between 65 and 88 passengers across oceanic routes, sparing human populations the supersonic boom generated by its Mach 2.2 speed. Nasa has a more outlandish test...

  5. A supersonic aircraft is an aircraft capable of supersonic flight, that is, flying faster than the speed of sound (Mach 1). Supersonic aircraft were developed in the second half of the twentieth century.

  6. Mar 29, 2024 · A supersonic boom is on par with a nearby thunder strike, which falls at around 105110 PLdB. It’s really freaking loud. And you can easily make it even louder. This 110 PLdB is estimated...

  7. Supersonic flight is the ability to fly at speeds in excess of the speed of sound. The value for the speed of sound varies based on air density, but at sea level it is 1,224 km/hour. Fly slower than this and the flight is subsonic, fly faster and it goes supersonic.

  8. Dec 6, 2022 · Imagine flying faster than the speed of sound. With its X-59, NASA could re-open the door to supersonic travel, this time without the explosive boom.
