Until reading this I had completely forgotten that back in the late 80's during an airshow at Homestead AFB, I walked into an "open" hangar (door was open just enough for me to wiggle through) and climbed up onto an F-16 while my friends were frantically trying to get me to come back out before I got my ass hauled off by the security that for some unknown reason wasn't anywhere nearby.

When I got back out my answer to their "are you nuts?" remarks was "well, they left the door open, what do they expect?"

And, yes, I'm also going to recommend Skunk Works I loved the quote from one of Kelly Johnson's engineers, "that man could see air."
