Well said DS. As for:
"I was on a VC10 where we had to jump down the emergency chutes. Who was at the top directing the pax to jump? The MAMS Fg Off and Sgt. "
I re-iterate:
"I would most certainly NOT allow movers on my aircraft to direct pax in the event of an emergency evacuation, as THEY ARE NOT QUALIFIED TO DO SO"
Important bit in capitals, for the hard of thinking.
Movers are baggage / freight handlers. Nothing more. So stop pretending you're anything else.
