Engine makers sound downbeat on supersonic, leavin...
I know nothing about Boom, but the "high bypass supersonic" thing raises the obvious question, how do they avoid the drag from the large (by definition) cross sectional area of the high-bypass fan?

I'm not privy to what Boom is doing, but variable intake geometry easily takes care of this.

They actually wanted medium-bypass engines. Low-bypass relative to modern airliner engines, but high-bypass relative to supersonic military turbofans.
