When Boom was first posted here I recall the narrative also including a lot of drag dynamics that would reduce the "boom" which would allow for more feasible overland routes / less noise pollution. Not sure where that sits now - I don't see it as much in their PR copy.

It's still their plan, AFAIK, but the regulatory hurdles to let them do it probably means it's a lot further off than overwater flights.
