I have a postscript to the story of the mooning DC3 pilot losing his ATP. I read about the story in an early '80's edition of 'Pilot' magazine in the UK - they had an excellent 'Letter from America' penned by the aviation writer Stephen Wilkinson - and very good it was too. Anyway, Wilkinson had written how, somewhere in Hicksville, USA, a pilot in a (stationary as I recall it) DC3 on the ramp had mooned a party of Boy/Girl Scouts. The female Scout leader was outraged, complained to the Feds (why? Why not his employer?) and the Feds pulled his ATP over the "Good moral character" clause, leaving him with a Commercial. (Interesting how the childish act of mooning upset the Feds in this context, yet generations of airline pilots serially cheating on their wives with the hosties did/does not, but I digress).
Skip forward 8-10 years and I wanted to get a US ATP so I called the resident FAA man who was embedded with the CAA at Gatwick to ask him if he had the power of an FSDO, and could help me sign off on the paperwork required before submitting myself for the exams and flight tests. Yes, said, he, and an appointment was duly arranged..
I turned up, and after an exchange of pleasantries we got down to it. He had the form in front of him and started asking "Do you have 1500 hours total?", to which I replied "yes" - tick, "Do you have "300 hours cross country?", "Yes", tick - and so on until, with a funny little grin on his face he looked at me and asked "Are you of good moral character?". I replied, straight away, "Well, I haven't hung a moon out of the window of a DC3 lately if that's what you mean". This obviously startled him and he said "You know about that?". At this point it was on the tip of my tongue to say "Yes, what dedicated anally retentive puritan in the Feds pulled that man's ATP for a foolish prank?" when he said "I was officer involved in that case!"
