I wonder how historically accurate the fall arrest harness on the one guy is?
I though back in the day when they would have been building Omaha, a harness was simply a thick belt around the waist attached to a rope.
The fall arrest harnesses of today have the attachment point between the shoulder blades and have a bungie like on this statue, or else they have a strap that's sewn in such a way that the stitching will tear out and gradually slow the falling person instead of having them come to a jerking stop.
I tried looking up the history of fall arrest harnesses, and only came up with
this short blurb.
