NASA

Head guy: Wow, we got it up there.

Other guy: Yeah, now we have to check for damage from the shit falling off.

Is it because I fix things for a living, or does anybody else have a problem with this?

A 1 1/2-inch-wide bit of tile captured on camera appeared to fly off the shuttless belly, on the edge of a door that encloses the nose landing gear. It was not clear if the tile had been struck by anything. Pieces of tile, which protect the shuttle from searing heat on return to Earth, have been lost on past flights without preventing a safe homecoming. [my emphasis]

If an inch and a half piece of tile can critically damage the fucking thing, why the fuck is it flying? Especially since little shit falls off the thing constantly on takeoff.
