Wish I could say I did. Maybe you'd know more about it than me, based on your screen name. The Gump I've worked with is a great dude.
The screen name is a bit of a premonition. When I get a call sign, unless I do something deservingly stupid (and that's a good bet) I'll have to remove the "dont".
I met a "Gump" during a helo fly in. Wore an orange flight suit, blue polo under it, and said his mission was to "piss off all the tightwad XOs within hearing or sight distance".
I wouldn't mind sharing callsigns with a guy like that.
