There's a video I saw just a few days ago, I'll try to dig it up, of a test that was done of a reinforced concrete wall. It had something to do with a nuclear reactor, I think, to protect the reactor against attack. To test it, they attached an F4 Phantom to a sort of a sled, and flew it straight into the wall. You can see it in slow motion and from several angles, the jet simply *disappears*. From the side, it looks like it is flying into a tunnel. The only thing left even somewhat intact are the tips of the wings, which stuck out beyond the edges of the wall. You can see them continue past the wall in a nearly straight line, as if they were still connected to a plane.
When it comes to an impact with a solid object, modern aircraft are not nearly as strong as you would think.
EDIT: Found it...
