One project last year I remember dropping a nearly-full reel of cable (Romex-type) between the ceiling joists. It went clean through leaving about a 2 ft. jagged hole, plaster dust over everything below.

Fortunately, the ceiling was old and crumbling and was going to be renewed anyway. Phew!

I've drilled through into the wrong place a few times and had a bit emerging the wrong side of a wall (into new paint and paper usually).

One of the perils of the very old buildings here in England is that brickwork and plaster can be very weak and crumbly! I've often been trying to make a nice neat job, only to have a ton of plaster fall off an old wall as I've drilled into it.

We should have an ECN motto:
We do not make mistakes. We create opportunities for amendments! [Linked Image]
