Why don't you just get a heli, go up, zipline down to the top and grab the prongs? Then, you could probably parachute down lol
My brother in-law used to do something similar to this. He never climbed this high, but he went far! In some point in this video, the guy doesn't use his safety harness and instead free-climbs up to the top. If he had let go, he would have plummeted with no safety. my brother got out of that job, even though the pay was nice, the people he was with were 90% of the time drunk or high xD
My English teacher actually was going to have this job, untill he decided to become a substitute teacher, then a full teacher. Heights never bothered me that much, although this would be terrifying.
