There were certainly elderly French Mhystere IVs at Sculthorpe in the 1970s (forget exactly when) and I understood they were US-funded and had to be scrapped, rather than sold on to a possibly less desirable third party. I don't recall any Vautours there though.
I remember seeing them at Sculthorpe, along with F-100's and some others. Why was Sculthorpe used as a dumping/disposal field ? Also does anyone else see the Vautour as a mini version of the Douglas B-66 bomber ?
