I watched some airport maintenance guys adjust a conveyor diverter by removing the side rail so the could see how far it could launch a bag.
I believe it. Even back when I worked in that business briefly in the mid 1980s (Hudson General), that kind of stuff was going on. I remember one time in particular a bag was opened with women’s lingerie. Guys were pulling various articles of it over their heads and trying to smell the woman who wore it. Savages! Supervisors always looked the other way when that stuff was going on.
