Remember Apollo 13? Or the AF Concorde that had tools left in the fuel

This is sort of a cliche, but it actually happened with one of our club's
1-26s. They had been making some kind of repairs on a wing that required
riveting new sheet metal on. When the wing was picked up to move it back
to the glider, there was a God-awful thump from inside. The glider went
through the rest of its life with yet another patch just ahead of the
aileron where they had to make an access hole to get the bucking bar out.
