A few months ago, I saw a press release with renderings of the Grand Canyon Skywalk and was very impressed. When I read through the release and saw the 71 million-lb, “71 fully loaded Boeing 747s” statistic, I punched a couple of buttons on my calculator and dismissed these claims as unfounded early Internet blab. To see the same stats in MSC (July 2007, p. 74), a respected industry publication, astounds me. I don’t know where those numbers came from, but they are undoubtedly false. I would be very surprised if the walkway’s live and dead loads totaled over two million lb past the edge of the cliff. Run a few quick numbers yourself.
