I bet the wind is a bit more at that height than at 3 stories. Mostly mental I guess...unless you do this 40 hours a week.
I obviously have no Native American blood running in my veins ... the photos from that boom give me the willies!

Looking at the third photo, you can see Tower 4 going up on the left. Eventually to be 977 high, it will be the fourth-tallest skyscraper on the WTC site, 72 stories.
Just peeking out from behind Tower 4, you can see the nave and spire of Trinity Church, at 281 feet, the tallest building in New York City from 1846 to 1890. Alexander Hamilton and Robert Fulton, among many other prominent Americans, are buried there.
Aside from several buildings around the Church itself, Trinity owns a large part (40% of the buildings and 50% of the land) of what is known as Hudson Square, the Printing District or West SoHo.

I have been to Uncle Alexander's grave at that church-some very valuable land there.
Who was it who said "biggest waste of real estate-Churches and cemeteries?
When I worked on the Miami Airport Interchange around 1961 I was determined to overcome my fear of heights. One of the shorter bridges had some beams coming out of the fill and I tried walking a few more feet every day. The drop wasn't six feet into sand, so it was safe. Once I was over that I started getting used to the higher bridges, and eventually I was walking the beams 80 feet in the air, then jumping from beam to beam. This was before OSHA and when I was a way too adventuresome 20-year-old. The wonder is I survived some of the things I've done. Dumb!
I am not fond of heights, but I worked at a fuel alcohol distillary for about a year before I started survey where I climbed towers in the 100-140 foot range daily. Not the heights in the above pictures, but high enough. It somewhat got me over my fear of high places. I don't like them, but can cope with them. If you work in any situation, you somewhat get used to the surroundings, that can be dangerous too..over confidence.
I put in a proposal yesterday that will involve topoing a portion of the bluffline on Lookout Mountain. A fall would probably be fatal. Client is very concerned about us. I have developed some simple techniques for working such places. Could be done reflectorless, but too much brush which is another factor, plenty to hold onto or stop a fall, but not at all reliable enough to trust or count on.
Definately no comparison, but a typical day at the DFWC for sure

what is that, Stonehenge? 😉 that looks pretty unsafe, maybe worse than the OP pics...
Doesn't that project have a safety officer?
I know of one company that had a party chief thrown off a site recently because he didn't tie off (his instrument man was, but he wasn't). He was about 85 feet in the air at the time.
