Check out this directory of pictures involving accidents and screw-ups of every kind imaginable. It would be easy to spend an hour or two browsing through them all. But I think a few of them are of doubtful reality. For instance, this one of the California Highway Patrol is an obvious joke. And I can't imagine how this container ended up inside the engine. There's also this photo of a bird that collided with a plane. I believe it's real, but it's still a pretty odd picture.
