2. • • The sonic boom it created was so loud that the aircraft was forbidden from flying over land while going supersonic. Even today, while some military aircraft can travel faster than the speed of sound, civilian planes, because of noise, haven’t been able to exceed Mach 1 — the speed of sound — over land in the U.S. since the FAA banned it in 1973.

   Can a supersonic plane fly over US soil?

   • The FAA ruling still prohibits unlimited supersonic flight over US soil, but it does open a path for exemptions for testing the experimental aircraft. The US agency is also hoping to prompt aviation authorities in other countries to move in a similar direction, so that transcontinental supersonic flight could become reality in the next eight years.

   Can a supersonic plane fly over the sea?

   • He says that routes such as London to New York or Dubai are natural fits for this technology. 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 supersonic travel.

   What is a 'low-boom' supersonic plane?

   • Matthew Hutson writes about efforts by researchers at NASA, JAXA, and various private companies to develop supersonic airplanes that travel faster than the speed of sound while making only a 'low-boom' or 'sonic thump' instead of a sonic boom.

   Could a 'quieter' plane overcome bans on supersonic flights over land?

   • Nasa has also developed a "quieter" plane that it hoped would overcome bans on supersonic flights over land. Earlier this year, the Civil Aviation Authority (CAA), which oversees aviation safety in the UK, ran a consultation looking at the " ongoing development of new aircraft types capable of supersonic and hypersonic speeds".

   Can Spike fly a supersonic plane?

   • Spike says its "quiet supersonic flight technology" means it will be able to fly at supersonic speeds across land without disturbing people unduly. Spike will not yet reveal how it will do this, but it has chosen an airframe design with wings swept back at a 55 degree angle. Affordable supersonic?
