its covered with a heavy layer of dirt
Aprox 20 - 30 feet southwest of that tree (pointer) is the object in question. It looks like a single engine aircraft, wings intact but covered with a lot of dirt. I've measured it to be 25' by 30'. the tarp looks to be 20'x20'.
I don't know if it matters but I have a nVidia 8800GTX video card which is rather pricey.
