I remember as a Cranwell Officer Cadet on exercise coming across a couple of wrecks in the Derbyshire Peaks, IIRC the DS, who made us walk to them said that they were a couple of F86 Sabres. There wasn't much left of them and that was 20 odd years ago.
I can also remember finding a crash site in Scottish hills but I can't remember if that was whilst at school there or later whislt doing some RAF outward bound training at Grantown on Spey.
