Study: Did a 757 hit the Pentagon?

[madnak]

Whatever the object is, it disappears in later frames. And it fits the profile of a plane just fine. Image d looks very much like a plane to me. It also looks like the correct outline based on the original image. The two white objects behind the one in question are almost surely buildings in the background. Also, they do not move in later frames as the "image d" object does.
