The Federal Aviation Administration is proposing a rule change that would lift the decades-old ban on civil supersonic flight over land in the United States. Currently, it is illegal for commercial aircraft to fly faster than the speed of sound over populated areas due to concerns about sonic booms. This proposal seeks to replace that blanket prohibition with a noise-based standard.

Why it matters: This change is the first major step toward allowing faster commercial travel over domestic routes, but it does not mean supersonic jets will appear tomorrow. The rule establishes an interim standard to encourage technology development while addressing public noise concerns. Most immediate impact is on aircraft manufacturers and future operators who need regulatory clarity to design and certify new planes.

Who it affects

  • Aircraft manufacturers developing or planning supersonic commercial jets
