According to my Dad (who is clearly the most reliable authority in the world :-() the reason the Concorde failed is because Boeing lobbied the government to get it banned over the continental US so they could sell the 747. He's basically saying all that stuff about noise is mostly bunk pushed forward by Boeing to get rid of the competition. You'll note BTW the 747 and Concorde both came out around the same time and you probably also know the 747 was never designed to be a passenger plane. It was designed to be a military cargo plane but lost the contract to Lockheed's C-5A so Boeing needed it to sell as something else. He, my dad, claims the NYC to LA route was the most lucrative and that without it Concorde didn't stand a change. I have no idea if there's any evidence to back up his story. Maybe someone else out there has more info.
