BOOM'S XB-1 BECOMES FIRST CIVIL AIRCRAFT TO GO SUPERSONIC

Summary from the TLDR newsletter

Boom Superconic's XB-1 demonstrator plane went supersonic in the skies over California's Mojave Desert on its 12th test flight. It cleared Mach 1 and stayed supersonic for around four minutes, reaching Mach 1.1. This is the first time a supersonic engine has come from something other than a nation-state. Boom already has customers waiting for its technology when it matures. The company is doing some work with the US Air Force, but it remains focused on making supersonic passenger travel a reality again.
