> Noise means you can't do US domestic

Part of that was also political. It's petty and I wish it weren't true, but a domestic-made plane making noise will be better accepted than a foreign-made plane making noise.

Whilst this is true historically, the regulations exist and I don't see rewriting them to tolerate sonic booms as a vote winner, not even for those committed to arguing against the trend towards stricter restrictions on greenhouse gases etc. A lot more people will live near the flightpaths than use them

Do you have any sources to back that up? U.S. Congress funded development of the SST (Supersonic Transport) back in the 60'ies but stopped funding in 1971 due to concerns and displeasure of exactly the sonic booms (and ozone layer issues). So five years before the Concorde entered service a domestic plane was not seen as being worth.

Heppenheimer's The Space Shuttle Decision has a chapter where this is discussed in detail.
