Re: CONCORDE....HOW........IT..IS.....
NASA flew a TU-144 for a few months several years back, collecting data for the National Aerospace Plane project. The plane was returned to the Russians, and the NASP project is now on the back burner. NASP was to have been a Mach 15 airliner that could reach halfway around the world.
The Russians plagiarized nearly all of the TU-144 from Concorde, but they did add one innovation that improved the aircraft. They added the retractable canards, which added pitch authority during takeoff and landing. This also prevented the flaperons from levering the main gear into the ground during rotation, which magnified the load on them during the point of greatest stress. This was the primary cause of the numerous tire problems the plane suffered throughout its service.
Boeing was developing an SST at the same time Concorde was being developed.

It was cancelled mostly due to the fact that it wouldn't be allowed to fly supersonic over the continental US, and even over the ocean, it wouldn't be profitable. It was much bigger and a little faster than Concorde, and was to seat 300 passengers.
Boeing tried to solve the problems associated with a delta wing by trying a variable-geometry design. That would have allowed supersonic flight, while reducing deck angle as well as takeoff and landing speeds to normal. The design was too heavy, as the weight of the wing hinge assembly would mean the plane couldn't carry a profitable payload.
I don't think Concorde was ever profitable, despite $10,000 ticket prices. The planes originally had several dozen airlines interested, but the 11 planes built were eventually sold to British Airways and Air France for £1 each. The Concordes probably attracted extra business to those carriers due to their prestige, but they weren't profitable, since they burned twice the fuel of a 747 but only carried a third as many passengers.
It would be nice to see one returned to the air, since it was such an aviation milestone, but I don't think it will happen unless the UK or French governments sponsor it.

America did use a TU144 in the 90's to find ways of creating your own SST. You found the costs were too high so the project was once again scrapped.
