Les, we had a similar one in our neighborhood. The zipline had a rope you had to hang onto as you traveled down. My best friend somehow managed to get the zipline swinging as he went downwards and wrapped around his neck. I wasn't there, and have no idea how it happened. When he reached the bottom, he was wrapped well enough that his feet didn't touch the ground, effectively making a noose. Had a parent not been nearby and heard the kids screaming, he would have died on that rope. Afterwards he had the absolute nastiest friction burn on his neck that I've ever seen.
