- "The greatest obstacle is the refusal by the aircraft's manufacturer -- formerly British Aerospace-Aerospatiale, now Airbus -- to lend its support to a restoration," said aviation journalist David Kaminski-Morrow, air transport editor of Flightglobal.com.
"Concorde is an immensely complex supersonic aircraft and the Civil Aviation Authority in the UK will not entrust the safe upkeep of its airframe and systems to a group of enthusiasts, regardless of their passion, without this technical support in place.
"If it isn't there, the aircraft won't be allowed to fly. It's as simple as that."
Airbus told CNN it had not received any requests from the Concorde group about providing support.
