Elon Musk supports scrapping FAA's supersonic flight regulation

Supersonic flight is currently restricted over land in the United States due to the loud sonic booms produced when breaking the sound barrier. These flights are only permitted under special circumstances with specific authorization. Concorde, historically the only commercial supersonic operator, never received such authorization for regular operations due to concerns about noise impact.

The removal of this rule could potentially expand route options for supersonic flights, including domestic routes like Los Angeles-New York or international routes such as Chicago-London.

Boom Supersonic recently achieved a milestone with its XB-1 demonstrator completing its first successful supersonic flight from Mojave Air & Space Port in California. This marked a significant achievement as it was developed independently without military or state involvement.

NASA and Lockheed Martin are also working on quieter supersonic technology with their X-59 aircraft, which aims to reduce noise impact by emitting more of a thump rather than a traditional sonic boom.
