Not my work, but I used to work as a miner on a Station in the outback, and one day one of the work utes got a flat. One of the young Geo girls swapped on the spare tyre but didn't do the wheel nuts back up properly, only finger tight. about 6 hours later 2 vacation work uni students were driving the ute off to do some field work and the wheel came off as they were driving down the road.

After calming them down we called the mechanic and he drove out, swore his head off at us for being stupid (I had nothing to do with it ), dragged his mig over and welded the wheel onto what was left of the stub axle...

That's pretty dodgy, would hate to be the person that tries to change that wheel next.
