1st cit, a glacier is a good place to hide something from the dmg cause by enviromental forces like wind, rain etc. look at the mammoth in sibiria.
And stories about planes coming home after incredible dmg are there for every type of plane.
He are some i found while reading the histories of JG26 and III./JG54
A fw190 collided with a spit in midair, losing the outer quarter of the the wing and the aileron, pilot had no prob to fly home and land it safety, the spit fell apart and crashed.
Another one was hit by 20+ 0.5 cals, coming home with the pilot not even noticing them and landing back at base. There they discovered that 3 0.5 had torn through one prob blade, 2 were stop by the pilots seat armor etc.
In Op "Bodenplatte" a D9 pilot had the bad luck to collided with a tree when flying in low level. Cutting of last 4 meters of the tree. returned home with the plane vibrating a bit, when landed, i was found that each prob blade was "a bit" shorter than before.
and so on and so on
P.S. i agree the vertikal stabilizer of the P38 falls of if u only look angry at him, this should be fixed
