OK, I'll take a shot - btw, great post Albie. I don't care what kind of airplane you flew or which service you flew it - fighters, heavies, helicopters...Navy, AF, Marine, Army - if you served, we're probably going to have a good trip together. I didn't say always, I said probably. If you're a civilian, you can be a good dude and a good stick as well...and it can also be an enjoyable trip - but it will never be the same as flying with another military guy - and here's why.
Military guys serve in our armed forces because they believe in our country and our ideals. We choose, when we sign the dotted line, to put our lives on the line if so required, i.e. selfless service. There is a common bond - a brotherhood - that lives deep down in us, whether it was as an enlisted guy in the Army or a fighter pilot in the Navy - that we will always share, and that no civilian can ever understand. It's a silent pride thing - I don't think I'm a better pilot or person than any civilian - but I will always have a place in my heart for the love of my country and all that I sacrificed in order to achieve it. Civilians CAN be true patriots as well - but never to the same "aspect" of the military man - especially one that has lost brothers in both training and combat (which I have and many other military folks on this forum have as well).
As far as flying a trip with a military guy - well, I typically enjoy it more simply because we have a common background. There are a bunch of civilian guys I've flown with as well that are a true joy to hang out with and fly a great jet. But for all the civilian guys on here that badmouth military guys because they're "d*cks, dorks, etc"...never forget he served his country honorably and has lost brothers in the line of duty - and that's something you have never experienced.
As a side note, the book "Lone Survivor" does a great job at explaining in detail what I just said.
