         A 
         result of the cold war's technology rivalry when the Soviet Union 
         copied many things the west made including the Concorde and Space 
         Shuttle. The Tupolev TU-144 was one of the Soviets least successful 
         project. Built as a competitor to the Anglo-French Concorde from 
         modified plans stolen from the French it was the first supersonic 
         commercial aircraft beating Concorde by two months.  
          
         The programs first disaster was when a TU-144 (or Concordski as the 
         media called it) crashed in front of TV-cameras during a presentation 
         at the Paris Air Show 1973. The French had sent up a Mirage III jet to 
         photograph the TU-144 in flight, but did not tell the Russians. The 
         plane found itself on a collision course with the Mirage when they took 
         evasive action the plane stalled and then when they tried to recover 
         from the stall they overstressed the air frame causing the plane to 
         break-up and crash, It was also suggested that the pilot who was under 
         pressure to show off the planes abilities against the Concorde, 
         possible was pushing the plane too hard when he attempted the steep 
         climb that caused the stall. 
          
         After several modifications the Concordski was put back into service on 
         mail and cargo runs as the TU-144D between Alma Ata and Moscow in 1975. 
         The Russians wanted to prove the plane was safe before starting 
         passenger service in 1977. A second crash soon after passenger service 
         began put commercial service on hold again in 1978. while a third crash 
         landing sealed the fate of the TU-144 with the last jet to fly in 1985.
          
          
         The TU-144 could hold 40 more people than the Concorde and was slightly 
         faster but it used more fuel and had less range, only 17 TU-144's 
         including 1 prototype and 5 TU-144D models were built, while there were 
         16 production and 4 prototype Concorde's built, 14 of which went on 
         sale to Air France and British Airways. 
          
         The TU-144 flew again in the mid-1990s, when Boeing and NASA partnered 
         with Tupolev to test supersonic flight. using a heavily modified 
         TU-144D was renamed TU-144LL and set up as a flying test laboratory for 
         future supersonic development. Developed for NASA's High-Speed Civil 
         Transport program it made 32 flights up to 1999 near Moscow. Since then 
         Boeing has shelved plans for a supersonic plane deciding to continue 
         improvements on their 777 series jets. NASA's part in the project has 
         also stopped as their hopes for large scale use of supersonic aircraft 
         had proven too costly.
