The aircraft was sold into the care of eCube on the basis that it had a preservation plan but it now seems eCube had failed to secure funding to do that.
It had been planned to give the public access to the aircraft at a site outside of the perimeter of the airfield but it now seems Yankee Charlie is destined for the profit rather than preservation.
Landor is now kept at Dunsfold under the care of a TV production company and Negus has been converted into a conference and party venue at Cotswolds Airport.
The move could prove especially disappointing given there is already an established aviation museum, South Wales Aviation Museum, on the site.
Attempts have been made to contact eCube but calls have not been answered. British Airways has also been asked for comment.
