I wonder how many of those 12 year old kids go up that chute with a shedding glacier hanging above them? I'm thinking exactly zero. I'd go as far as saying experienced climbers would decide they have better things to do elsewhere.
Even if one were daft enough to ignore the hanging glacier above, that obvious avalanche path starting above then going beside and below the plane sets the ground rules for climbing in that area. Looks really dangerous to me.
Alive, do whatever is possible. Dead, forget about it. The mountain owns him and the plane. Leave him there until he comes down somewhere accessable even if it is 100 years from now. I know I certainly wouldn't want anyone coming after me in the same environment unless I'm sitting there waving my arms around.
