“ BTW. Ever heard a sonic boom? It’s a thunder clap right next to your head. You really don’t want them flying supersonic over your house, unless you own a window replacement company. ;~))”. You are mistaken. Years ago, Concorde was flying over my house every Sunday around 2 pm on its way to landing at IAD, and there were no sonic boom, just a thrilling sight.
The Concord did not fly supersonic over land, only over the ocean. That was agreed to before it began operations.
