If supersonic flight ever returns, my money's on Emirates or Qatar to try it.
What's funny about these discussions is listening to the British and the French piss on Boeing:
The 2707 was basically a big damn F-111.
Hey, maybe we can talk about what actually happened?
Note that the Concorde was no quieter... But when the FAA won't allow your plane to land it's hard to sell that NY-Paris run. Hey, why else did the 2707 die?
Note that they weren't going to subsidize the planes.
Note that that was $8k on top of an absolutely gob-smackingly high price:
Doing the math: the real cost of the Concorde from DC to Paris and back was $28k. The primary difference between the Concorde and the 2707 was that France and England were willing to blow a billion dollars a year so that rich people could pay half-price (odd for such a peculiarly socialist system).
I've got a 165-page sales manual on the 2707. I've got... pretty much all the sales literature on that thing. And even in 1965, you look at it and go... "this is a giant government subsidy waiting to happen." And in 1971, the United States went capitalist while England and France went socialist. And there we've been ever since.
