There was a recent Mythbusters episode in which they had a Wallenda tie in. They ended up rappelling down a canyon wall with nothing but duct tape. As far as I can tell they didn't use any safety ropes in case the duct tape rope broke. They are always pretty open about whatever safety equipment they use, so they had no reason to hide the use of a safety rope. Assuming I saw that correctly, it was impressive, but also bonehead stupid as well.
I saw that, and they have tested the tensile strength of braided duct tape in past episodes. I'm guessing the safety factor of their weight vs. what the tape would actually hold was 3X-4X. As you know, they have stopped short of some tests because of what their insurance carrier would allow, so I'd be shocked if they just went in "hoping it would hold".
As far as walking a 2" wire 1500' in the air, I'd be more impressed if he did it without a balance pole. A stunt with a safety cable, well that's not really a stunt IMO.
