I was flying from SYD to LAX over the weekend, and we had the worst turbulence I've ever experienced. There were only a couple scary bumps, but there was a moderate chop that lasted for at least three hours. The guy behind me told another passenger it was the worst he had seen as well.

I was amazed by some of the people who could just sleep through it or, better yet, some of the people who got out of their seats while it was happening.

What's weird is the flight crew were never asked to sit down, even though I can recall two transatlantic flights when the turbulence was less severe yet meal service was interrupted. One FA looked nervous but of course told me I had nothing to worry about.

Is this true? Am I crazy for thinking the pilot is going to lose control of the aircraft or getting worried at all?
