My dad was in the Air Force for the first 14 years of my life then retired.. so... when we lived in Alaska he got his pilots license and we went out in Cesna's and shit all the time. When I was 10, I was with my dad in the hangar at Elmendorf AFB bored while he talked to some dude, and the base commander happened to walk in and asked me if I wanted to fly. Sure, why not? So I hopped in the pilots seat, and he instructed me how to take off and land, we went through all the pre-flight checks, and with him to my right I flew for about 30 minutes. Of course both pilots have full control, but he only stepped in and helped during the landing.

As far as commercial flights, we have taken hundreds of military "hop's" around the world.. anywhere for 5 bucks.. cant beat it. Flown in all sorts of different planes including a C5 (obviously big and LOUD as fuck), and a KC135 refueler.. I was asleep but my dad and brother got to go into the refueling cockpit while it filled an... shit is that an F-18? I dunno, Ill attach a pic.

EDIT: I decided to attach the pic my dad took of me sleepin on the fuckin plane. While we were still climbing to cruising altitude, I wrapped my head up in that cargo netting and passed out. I guess at some point my head fell out lol :P
