This is very exciting,remind me of Concorde. There needs to be more private companies pushing the edge of what is possible. SpaceX is doing that with space travel and I feel there are similar opportunities in commercial air travel.

I think one of the main goals of NASA QueSST program[0] is contributing to making commercial supersonic air travel happen.

And there's a lot of private companies contributing[1]. But makes me wonder where Boom/Hermeus/Astro Mechanica etc fit in.
