I had read somewhere that there were some political issues: Concorde was built primarily for cross Atlantic trips and reduced travel time very considerably. The US didn't have a supersonic airliner and didnt want to be seen as behind the times technically so excuses were found - noise abatement, primarily, to disallow it's use within US airspace.
I don't know how true that it, but it sounds to be about par for the course.
Noise abatement is a real issue at KTOA, Torrance airport. Need a really steep climb to prevent fines.
