Heh good times. I have a few memorable tower climb stories (memorable to me, and if I don't tell them every so often I'll likely forget!)
About 10 years ago (sheesh has it really been that long!!) I was working for a startup doing some pretty nifty wireless technology (the startup failed, but the technology was good). For test deployments we had a spot a good ways up a 160' tower and a few shorter towers/buildings. Now I certainly do realize that 160' isn't nearly as tall as this is but... we would routinely free climb it and then rappel down. After you get over about 30-40' it didn't seem to matter much, its just tall. Was the only job where I've ever actually been paid to rappel and write code though
The worst really is at the top when there is nothing above you... Nothing to get ahold of.
I was volunteered to help put the generator on top of my grandpas windmill (has to be over 20 years ago now although I can't recall exactly). This involved climbing to the top and then bolting on a crane, guiding the motor into place and then bolting it down. The tower was only about 35' high but it was on top of a 200'+ very steep hill so was basically 235' of "down". Not to bad so far.. then came the blades
Hauling them up wasn't to bad, but to bolt them on I had to sit astraddle the motor and lean waaaaaay out over and down to get at them. First one was pretty good since it was blade down, second one not to bad since it went mostly blade down once I got a bolt in it.. The third one had to be started blade up (these are a good 10'+ long) which involved some amusing tie offs to the crane and holding it in place while half upside down. Was a little nerve wracking (yes I was tied on, but it still feels wrong to let go
)
Oh yeah, if you're in this sort of a situation DO NOT drop a screwdriver, they really get up to speed on the way down. I had one just miss me; hit the ground with a nice THUNK.
