 CONT: Commenting his descent deeper into the break, Joe says, "I  didnt put a knot into the end of the rope. If there was nothing  down there, I would fall, and it would be quick." Two minutes before  (approx. at 54:30) he is throwing the end of the rope into that  break, and as it falls, we see clearly that the knot is properly  tied at the end. Just as safety rules prescribe.
