Besides Concorde, what other supersonic airliners exist, or used to exist?
There is another, Konkordsky, (Tu-144), which was made out of a stolen plan of Concorde (the 2ºplan)…It had many problems, and Tupolev (the best russian flight engineer) was unable to fix them, so it crushed in Paris-Le Bourget in one exhibition trying to climb after a stall I think…The structure couldn’t resist the stress…I think the 7E7 from Boeing was meant to be a supersonic flyer, but I think it didn’t even fly…
The Russians built a Supersonic plane that was bigger than Concorde – often called Concordski (I beleive they may have stolen the plans for Concord – they look very similar and it was during the height of the cold war). Its proper name was the Tupolev Tu-144 and it made its maiden flight in 1968. Unfortunately it crashed at the Paris air show in 1973 – which lead to it quickly being scrapped. Especailly after the modified Tu-144D also crashed in 1977. The Russians are working alongside the west on the TU-144L – but whether this will ever see the light of day (Concord was a great plane but not a commercial success) – will remqin to be seen in this hopefully “greener” world.
