Yes - it was a smooth flight, then suddenly started shaking - then sideways, then going down slightly, down a bit more, shaking more violently, down even more and getting worse and worse. Suddenly seat-belt lights, and engines roar. It was climbing whilst going through the turbulence. It scared the hell out of me, my two younger siblings (8 and 6) were crying and grabbing on to my arms and screaming in very loud Polish!!! I wasn't the only one to be scared though!
