They slip!!!
Many years on rock and ice and this is one I would pass on.
Right after Goodwin did Sears tower I was out with friends and their friend was a TV reporter who had been inside Sears. He was 100% sure that the vacuum cups were sliding on the glass! Few years later I met Goodwin at the local cliffs. he said there was a grease film on the glass that made them slide!
