A friend's son earns a fortune polishing wind turbine blades. They get pitted, so the surface needs smoothing out occasionally. Best pay seems to be out in the North Sea. Wouldn't fancy that. Don't like heights. He also flies to Australia to clean and fix skyscrapers in Sydney.
I spent a week down a deep hole that was OK. It was for the foundations of a pillar for a motorway bridge. Must have been 30-40 feet deep. The job was to make it deeper with a pneumatic drill. Only, the noise in the steel lined hole horrendous, even with ear defenders on. There always had to be two down the hole and one at the top on watch. So we just didn't do it, unless the one at the top warned us the foreman was coming. No-one was coming down the hole to see how deep it was, and it seemed no-one thought to check how much we brought up. I read a whole stack of Beano's and a bit of Macbeth.
