I think it's always a little unfair to acuse the Tu-144 of being a Concorde clone - yes it's superficially very similar, but it did fly first.

Yes, but the Soviets DID base their design on the Concorde, NOT the other way around.
The Russians rushed the 144 into flying, and hence, beat the Anglo-French at the game.
How many revenue flights did the -144 ever do? ANY?
Paris certainly ended it's career - why? Was their an inherant design flaw that the Soviets could NOT overcome, so merely shelved it? I know the second -144 is being rejuvenated to fly, I think for NASA, and needed SIGNIFICANT upgrades, not merely in the avionics suite.
