Dude, stop making us all look bad. There is no freakin' secret to jumpseating. You are supposed to show your company ID, License, and current medical. If you use a little common sense, you will hand this all to the Captain along with your j/s pass when you introduce yourself to the crew and ask for permission to ride on their airplane. If the captain doesn't care to see your license/medical no big deal, but you need to offer it.
As for the whole military vs civilian sidetrack, most pilots with a civilian background learned the rules and etiquette for jumpseating as they worked their ways up the ranks. Most military pilots have never ridden a jumpseat and need to take the time to learn how to go about it. It is covered in basic indoc. at FedEx. Maybe some of you slept through it.
And to everyone else...sorry about the 1-hour show rule. That applies to us as well as off-line j/s's. You aren't being picked on.
