This is so bad, you can see they could never climb it without a grapple and if I remember right there is an antigrapple their wall is missing as well
I just rewatched the video and I counted seven times where Lucy relied on the safety harness to support her climb. . . and at the final moment she twice used the safety harness rope to pull herself up onto the top.
I also like how they claim they say they don’t recognize the people the government used in testing the wall sections who said they had the most trouble getting over it. These people didn’t recognize the testers who made these claims from their climbing magazines and climbing sport community, so they conclude they must be fakes. Did they fail to notice where it said the various wall samples were tested by Navy Seal teams and Special Forces members with special training, not sport climbers, i.e. trained mission specialists who I’d bet have better climbing skills than weekend rock climbers. This design was found to be the most difficult to scale.
I know one of those guys whose idea of fun was free climbing sheer rock walls with no ropes. I saw a picture of him once hanging from a 90° horizontal rock jutting straight out over a thousand foot drop, working his way toward the equally sheer straight up rock face, which he intended to climb, with just his fingers stuck in cracks in the rock. He did this with a little bag of specialized clamps and rosin for his hands and shoes with toes. He once taught cadets at the academy how to do it. His dad was one of my clients. He’s now an eye surgeon, but still goes free climbing every chance he gets. I doubt he’d try this; no cracks.
