Amusing in hindsight - at the time it wasn't really so funny: flying ATL - MEX on AM at the end of 2004 we ran into apparently completely unforseen severe weather - the absolute worst turbulence of my life. By far. Out of the 6 people in my row, 4 had to make use of the barf bag... Apparently the Navy or Coast Guard had to take over ATC because all the planes in the area were totally off course. Anyway, we were thrashed around for a good 30-40 minutes while the pilot was trying to us the hell outta there. After it was over, and things and heart rates were back to normal, the pilot comes on and says: "I know you all we scared, and you know what? So were we!..."
