Most of AF Concorde are still intact except for couple but all BA Concordes were drained from all liquids plus there ground power connectors were removed. "AC" was re-lifed when most of its electronic systems were powered up again couple years ago by Concorde diehards but due to internal politics between 2 groups it was put to sleep again and museum was told by BA not to let it power up again.....
I'm skeptical about RTF again, I have to see it to believe it. I can see RTT under there own power is possible easier then RTF...Lets see what happens as BA still have there backs towards these marvelous aircrafts. If there is ant RTF Concorde, it will most likely from Air France fleet..."F-BTSD" more then others as its kept alive electronically with most systems still operational on it.....
