EGNX and Jake reminded me of a couple of stories from when I was flying. For my aerospace class in high school, two other students and I along with an instructor were taking a three legged cross-country flight, and right in the middle of one of the legs, the instructor turned to us and asked if we'd ever been zero-G, and we all said no, so he took control of the airplane and quickly pushed the yoke forward, and we dropped like a stone. It was an intersting, and exhilerating experience, to see the maps and pens and things around the cockpit start floating in front of your face for even a split second. Ever since then I've wanted to try that again, but I don't think I could ever do that to myself in an airplane, at least not until I get a few hundred more hours.

Another experience I had, was when it came time to do my night cross-country flight. During that day, there had been some rather nasty storms all around the area, but by that evening, the last storm had started to move off to the east. Coincidentally, the airport my instructor and I were flying to were off to the east also. So I got to the airport around 8 PM and we talk about whether or not we fly with the storm still relatively close. We decided to go as the storm was moving more north-east, and would probably be out of the area by the time we were airborne. So we took off, and got a flight-following from Madison ATC. As we were flying, we could see distant lighting flashes way to the north, so we called ATC to see if they had any weather near us, or in our way, and they said the radar was totally clear. So we kept going, but about a minute or two after hearing from ATC that there was lighting or anything in the area, the entire airplane lit up with a huge flash. I just sat for a second to figure out what had just happened, and whether or not we were still flying and everything was still working, which we were, and everything still was, so I wasn't too phased by it, until I look to the right at my instructor whose eyes were like dinner plates and he had that "holy-s**t" look on his face, which freaked me out a bit. But everything was fine, and we didn't hear any thunder, and ATC said they still didn't have any lightning flashes on their scope. So we figured it had been a discharge of static electricity or something that had built up on the airplane, like St. Elmo's fire. So that was pretty interesting. Also interesting, was the odd ~70kt headwind we had on the way back up at 4000 ft, when it was calm at the surface.
