Not a military aircraft and in a different area of the Sahara but a example of what can happen is the site of the crash of HP Hermes Horus G-ALDN. The aircraft crashed on 25 May 1952 in what is now Mauretania.

Planemike

Last I saw of the aircraft in an article, it was extensively stripped by locals, then buried by the sand. (Am I remembering that correctly?)

As such it’s probably a good example of the condition of any surviving aircraft in the region.

Pity, it would be nice to use parts to add to the fuselage at Duxford.
