Agree wholeheartedly with skidkid on this one. Did the one in Beaufort twice, and with all the aircrew parties and what-not, the Phrog crews for the MAGTF demo were looking at us with a pathetic look on their face as we were drinking our faces off and they were inside their 12 hours. Hell, you don't even have to be sober/not hung over when you man your aircraft. Just pound water and aspirin to be ready for the remainder of the evening.
As for made up answers, here are some of the favorites I've told kids (WAY more gullible than adults):
Yes, the triggers on the Cyclic are for our rockets. (I really didn't think they wanted to hear "1st detent is ICS, 2nd detent is radio)
Pitot Tubes are machine guns
Cargo rollers are for bombs
And my all time favorite:
The Optical Sensor Converters for the AAR-47 are actually scanners that read the passengers ID cards so we have an updated manifest. After I said that one, the kids father looked at me and said "Seriously?"
