I've seen articles on this over the years and the whole incident seems to have one of those "We didn't have anything happen here move along" vibe. In 1994 at RAF Boscombe Down a dozen or so people saw what looked like a diamond shaped aircraft crash or have the nose wheel collapse on takeoff. They all described an aircraft partially covered in a tarp but 4 engines were visible with twin inward canted tail fins in a hangar. Accounts list the airspace as then being closed. From reading, the first published data said A-7s training crashed then, no aircraft crashed then a couple of military Helicopters crashed nothing major. Apparently witnesses said a Lockheed C-5 showed up to take the "cargo" along with a Boeing 707 that was owned by the DOD I think. It's interesting that to this day a supposedly 31-year-old crash is still cloaked in secrecy yet the F-117A, and other aircraft have been declassified and been shown to the public. It makes you wonder what technology we don't know about. I think it was the National Geographic special on Area 51 where a previous employee said that there is a museum of defunct aircraft projects, which if true would be awesome to see. I'm curious what will be revealed years or decades to come.
