Earlier quoted context omitted.
Boeing engineers should leave and start their own company. "American dynamism" is hot right now and there should be ample funding available. Lots of the old dinosaurs are being nipped at by nimble upstarts like Anduril.
Have you seen how much lambasting Boom Aerospace gets every time they come up? Starting a new aerospace company isn't for the faint of heart!
Supersonic travel is expensive and environmentally unfriendly, and it will probably always be, because it requires more energy, because physics. All that for the minor advantage of saving a couple of hours on select flights. What it means is that it is a privilege for the wealthy (because it is expensive for what you get), at the expense of everyone else (because of the environment). So of course it is going to be unpopular, except to the wealthy in question.
It doesn't mean Boom can't be successful because the public opinion is negative, if the rich can pay. I am still not convinced though, after all, Concorde didn't fail technically (and it still flew after that one accident), it failed commercially. Boom is not taking the easy path here, since it is a technically hard problem with a dubious market.
