Quite a few around and,yes, envy is the bottom line.
Went head to head with one, many years back. Wondered why he was so offensive. Later, in some article, somewhere, he was all over the place in his rayband aviators, Boss headset, LHS of something minor, telling the world what he did when off the AME chair..
Another one, took one look at me in my leopard-skin speedos, proud to have starved myself down from 12 stone to 10.5 (fighting weight for NASA Space Cadet programme for my height was 11st-3ilbs) and he smirked ;"Ooooh, bangin on the beef !".
Oh. Can't stop. Another, close relative, actually, was very proud of having been approved for his AME. Told me it was going to be fun checking out female Cabin Crew Applicants once attached to an airline.
Yes, Report them. Get them out of the system. Spoiling it for the really excellent majority who keep us airborne.
