Here is a board through a tree.. just for example (i a m lazy today):

Those boards can be deadly weapons all right. But a wooden board penetrating a wooden tree as seen in the photo is a poor example, for several reasons, including:
1. Wood penetrating wood is not the same as aluminum/plastic penetrating steel/concrete.
2. The board didn't disintegrate into nothing like the alleged plane did.
Let's say you took the piece of wood and carved it into the shape of an airplane, would it still glide into the tree?
