One of supersonic airplane Concorde's four engines successfully underwent testing by French experts this weekend, increasing its chances of a return to service, Ben Lord, of Britain's Save Concorde Group (SCG), said Sunday.
The engine was in excellent condition, Lord told the German Press Agency dpa. The other three Rolls Royce engines would be tested in the coming weeks at the air museum near Paris.
Both operators of Concorde, British Airways and Air France, retired the airplane in 2003.
Three years previously, Concorde had crashed for the first time its 27-year history, killing all 113 passengers and crew on board.
"There's no technical reason why the airplane couldn't fly again," Lord said on Sunday.
According to the group this would simply be in a "heritage capacity." It hopes that the plane could play a role in the opening ceremony of the 2012 Olympic Games, due to take place in London.
Several firms who were involved in developing and operating Concorde are interested in supporting the new project, led by SCG and France's Olympus 593 group, Lord said. Around 17 million euros (21 million dollars) would need to be invested.
