Pretty neat, there is a similar place near my house in Centre Co. where a hiking trail leads to the crash site of a air mail pilot who crashed in the 30's or 40's I want to say. People have piled up some of the wreckage near a stone memorial on top of the mountain, but it's nothing on the scale of the wreckage like your spot.
There is also a place down in Maryland in the Savage River State Forest where a B-52 carrying nukes went down in a storm in the 1960's. I've not been to the actual crash sight but I have hiked in to the monument along Poplar lick creek. I believe the monument is at a spot where one of the crew members bodies was found. If I remember correctly the crew was able to eject from the plane before the crash but 1 or 2 ended up dying in the woods from exposure during the bad winter storm.
