Here is a new experimental airplane. It's a civilian supersonic jet. The kicker is that no supersonic boom could be detected from the ground during supersonic flights.

It's first successful supersonic test flight was on January 28, 2025. The second successful flight was February 10. There were a dozen or so other test flights previously but I think these were the first ever to prove a boomless supersonic flight was possible.
