On the scale of nuttiness, that is only middling.
I used to work for a company that built microwave communications systems, and that included a microwave video distribution system. That involved a number of microwave amplifiers mounted onto RF towers of various heights (and no, I stayed on the ground). There were adventurous types that used to climb the towers and would install or replace the equipment. They were paid quite well.
First one is a guy who just came back down from about a 300 foot level on the tower. After he comes back down so I could sign him out, he asks "If I got a surplus parachute up to that 300 foot level, do you think it would open before I hit the ground?". He wasn't kidding. If you don't know, it normally takes a properly packed parachute about 300 feet to open. He was talking about just gathering the parachute in his arms, jumping off the tower, and releasing the parachute.
Second one is in the middle of a cold spell in rural Manitoba. Outside air temperature is -40C (which is still -40F), and there is a 40Km/H (24-25 MPH) wind blowing pretty steady. The tower is 1800' to the tip, and our equipment is at about 1200' level. The amplifier at the top of the tower has stopped working. We call around to the tower service companies, and no one wants to go up. One of the tower service companies says that one of their guys may be willing to do it, but it didn't come from them, and it will be a direct deal between the company I worked for and this guy. Anyway, the guy shows up, asks about what needs to be done, and starts climbing up. Took him 3 hours to go up (with an 80 lbs. amplifier strapped to his back) and about 2 hours to come down (he just threw the bad amplifier down). Deal was, when he got to the ground, he would have a signed cheque waiting for him. For about 5 hours of work, he walked away with $20K. Said it was much windier near the top, and that the inside ladder had some ice on it. Glad it wasn't me.
