What's funny about my scariest moment is that I can't even remember where I was flying or on what airline. I just remember I was sitting next to a uniformed pilot in coach who was apparently getting a lift. He was a really nice guy and we chatted quite a bit. Suddenly we hit some pretty rough turbulence. I'm not good with turbulence at all, but when I noticed the pilot not even flinching from reading his paper, I relaxed a little. The turbulence continued, however, and started getting a lot worse. I noted in another thread about seeing a FA get levitated off her feet briefly and then slammed in to the floor when we suddenly lost altitude. This was that flight. The pilot sitting next to me suddenly dropped his paper and I distinctly heard him mutter, "What the hell is going on" as he looked up towards the cockpit and then looked out the window at the wing. He acted like he was going to get up and go to the cockpit when things started leveling out. It was during these moments I thought for sure I was going to die. I figured if it was bad enough to startle on off-duty pilot, we were in trouble.
