I did that a few years ago. It was a trainer and not worth much, but I wanted the engine and radio gear. It was caught in the very top of the tree with the tail in a fork.
Someone mentioned that we could bring our shotguns and blow the tail off of the plane and it would fall to the ground. Well we shot several boxes of shells and only made holes in the plane.

I finally got a fellow with a bucket truck who got it down.
