Great shots! Imagine going for a wander in the woods, and suddenly coming across something like a FW190 !
Jim, if you mean the fourth shot, it doesn't look like a Blenheim just going off the nacelle and wing form - might be that B-25 from another angle, or perhaps a Japanese aircraft?
I'm wondering if the B-17 in the first shot is one which crashed into the hills near me, after the crew bailed out down near the Norfolk coast. The terrain looks very similar, and the one I'm thinking of was once in large 'chunks' like that,back in the late 1960s, before erosion and recovery left only small fragments.
