That’s hilarious! My time in the Air Force was similar. There were always people doing things you wouldn’t expect from supposedly highly trained and disciplined professionals.
If the Viet Cong were picking up your signals, they must have been just a bit confused.
After I posted this story it occurred to me that my flashing light conversation with T.D. was probably the only time that he and I "talked" during which he was sober. :-)
