The fact of the matter is that the YANKS (as I am british, and we made up the term, and I am still in the opinion what the yanks are an inferior derivative race, I have the right to use it, as many yank shows already states previously call Canadians inferior names) were EXTREMELY jealous of it, so jealous that they tried to come up with the knowledge to be able to produce a competitor, they couldn't cut it FACT there IS NO OTHER REASON!

CONCORDE DID NOT BREAK GLASS, IT WAS TOO HIGH TO BE ABLE TO BREAK THE GLASS, I have had EURO FIGHTERS FLY OVER MY HOUSE IN THE UK AT MACH 2 AND NOT BREAK GLASS, there is however a small tremor, not much, just a small one.
Yes the government did help pay for concorde, who wouldn't ITS A PIECE OF ENGINEERING PERFECTION!
The yanks were so jealous at one point they weren't gonna let it fly to New York for a number of months... why is that? Its on the coast, there's no reason, EXCEPT PURE JEALOUSLY. They only allowed it to fly into New York once the French said if it can't land you yanks won't be able to fly into any of our airports for any reason. FACT.
Now did Concorde have a good business model, yes and no, but did it surpass ANYTHING in Aviation, Yes. Please remember the airframe and engines are from the late 50's/early 60's! YOU COULDN't DO ANYTHING LIKE IT! NOT EVEN NOW!!!!
Boeing is screwed, Airbus is kicking it left right and centre. YOUR OWN AIRLINE WON'T ORDER THEM ANYMORE!
Now stop with this petty argument, YOU ARE WRONG END OF STORY
