FAA issues new rules for supersonic flight
Here's an excerpt from the article:
The U.S. Federal Aviation Administration (FAA) has issued new final rules to help pave the way for the re-introduction of supersonic commercial flight. The U.S. airspace regulator's rules provide guidance for companies looking to gain approval for flight testing of supersonic aircraft under development, which includes startups like Boom Supersonic, which has just completed its sub-scale supersonic demonstrator aircraft and hopes to begin flight testing it this year.
