Definitely. The commenter who can't believe supersonic flight is commercially feasible by the early 2020s thinks it's because we'll fly from London to NYC via space elevator and slow through reentry via "huge magnets." To be honest, I don't know enough about the science and business of flight to know whether this pitch for Boom is feasible, but I'm not as inclined to buy this particular argument against it after this point.

For the record, I hope Boom succeeds. When I was a kid I learned about the Concorde as the future and it's been a real shame to watch it stay in the past.
