An Egyptian Plane ?

Here is a very strange artifact. Maybe this is an Egyptian plane from a pyramid ? So let me see, Australian aborigines developed a airfoil wing section. Egyptians might have know about it as well. The Wright brothers invented the airplane in 1903. If anybody has any explanation please comment.

For those that are unable to view this Egyptian plane (?) you can follow the link http://www.catchpenny.org/model.html
