DISCLAIMER: The two Concorde of of Air and Space Museum are not for sale
Following recent announcements regarding the possible return of Concorde in flight, and the weekend of Heritage Days, the Air and Space Museum recalls the status of its collections.
If it happens that uninformed visitors ask to the museum reception tickets to Mars or Pluto, the idea to fly again one of the Concorde Museum of Air and Space is equally fanciful.
These two aircraft are part of the national heritage. As the Heritage Code, they are inalienable and imprescriptible, as are the Mona Lisa or the Palace of Versailles. The mission of the Air and Space Museum is to transmit to future generations, just like the 400 other aircraft and objects in the collection. The policy of the Air and Space Museum is not to maintain its aircraft in flying condition, to best protect these parts for some are unique.
There is therefore no question of the two Concorde of Air and Space Museum are sold, regardless of the financial offer, nor will fly again someday.
However, the two Concorde of Air and Space Musuem can be visited by the public throughout the year.
