All I have to say is that I'm glad that I don't have to feel too guilty for the only thing I can relate to in terms of nightmarish things.
Being the younger tech that I am, I do steady work at a middle school. One day, I walk in there, and E2 was obviously hanging lower than it should be (read: 8 feet off the ground with a 14 foot proscenium). My supervisor was also in the room and I asked if I could bring it up. Given the go ahead, I start attempting to find the handle to the winch- I ended up using one from another winch- and then proceeded to raise the electric. At first, nothing out of the ordinary, nothing startling, fine. Then, I start to notice that all of the cable is winding up on top of itself, all the way at the edge of the spool.
Instinctually, I know this is a problem, but I don't know how to deal with it- I can fix a spool of thread but not a cable with half a ton loaded on it! I then ask my supervisor what to do, and he says to continue, and that it would "fix itself." (Go ahead, fidget.)
NOW- HE WALKS OUT OF THE ROOM. The after school group I'm working with finally arrives, as well as the building manager (my occasional boss). I return to my winch, and start raising it up a bit more. At this point, it "fixes itself" by dropping 4 feet. This is accompanied with a loud set of noises as the structure caught the weight as the cable rewound itself around the spool. Of course, building manager comes right on stage when- on cue- my supervisor also decided to make the entrance into the room.
Meanwhile, the kids in the house are going ballistic. When is the last time you've been to a middle school? I don't suggest returning anytime soon if you can avoid it.
So, luckily, I have my name cleared on two lucky counts. First, I asked the supervisor first, so it was written off into the bureaucracy as an accident caused by miscommunication, and second, the school was due for renovation over the summer, so they were going to tear that electric out anyway. Lucky me.
Of course, only after coming back to the school the week after did I fully realize how much danger I was actually in, considering that the plywood mount for the winch had actually moved upward diagonally half a foot, with the bolts carving gashes through the cinderblocks. I had literally broken the auditorium.
Don't you just love new, naive, inexperienced techs?
