In the Army one year we were tasked with hanging up the Christmas decorations in the drill hall at Camp Slade near Oxford. The final decoration as a star to be hung from the middle of the ceiling. The Corporal got a ladder, and made a few of us burly lads hold it vertical. He then got the smallest lad and made him climb the latter to hang the star.
In order to maintain the safety of the small lad, the Corp tied a rope around his waist...and that's it. The lad climbed with this rope trailing down below him. I have no idea whatsoever how the rope was supposed to save him if he fell. IIRC the Corporal eventually left, and got a job in charge of bungee jump safety for Noel Edmunds Late Late Breakfast Show.
