There are a couple of other pictures that show it on a cookie sheet or 20 footer with a net over it. The box was supposedly a special box engineered for the 8000 lb drill bit, which is what it supposedly weighed. As I recall, it looked like it was under some other cargo so the loadmaster may not have had a chance to look at it separately. Depending on how much running room it had in the box before it hit the end, a separate strap may not have stopped it.
