It would cost 2m euros to allow Concorde to fly again
France's Museum of Air and Space has revealed that its announcement that Concorde was to return to the skies for a two-hour flight in June was a hoax.
A statement on the museum's website had said Concorde would make a special flight from Paris on 16 June, breaking the sound barrier off Ireland.
French news agency AFP picked up the story, only to retract it when it was confirmed as an April Fool.
The museum says it wanted to publicise a dream to see the plane fly again.
"This hoax launched by the Museum of Air and Space can produce ideas and make the dream live on," Gerard Feldzer told AFP.
The statement posted earlier on the museum's website included an "exclusive" YouTube video showing a Concorde leaving its hangar.
It said one of two Concordes given to the museum after their retirement had been kept flight-ready, and that technicians had made secret preparations for the demonstration flights.
Amid high demand, it said 50 passengers and three crew members would be chosen by lottery for the flight, which was to mark the 40th anniversary of Concorde's first French take-off.
Flights on the iconic, supersonic plane ended in 2003.
A new flight would cost 2m euros ($2.6m, £1.8m), Mr Feldzer said.
