I remember sitting in the back row in a 747 economy class cabin (Row 55 I think but I'm sure someone will correct me
) JNB-LHR when we hit turbulence somewhere over Africa. As the a/c pitched nose down the next bulkhead seemed a long way away. Cabin service was still going on as the turbulence was somewhat unexpected and a trolley rolled past with a CCM trying gamely to hold on to it, before it rammed a sleeping pax a few rows ahead. Not nice at all and quite entertaining in retrospect (though admittedly not for the pax with the bruised arm). The only time I've felt truly unnerved was in a F27 (remember them?) BFS - EMA on a really vile night. We got into EMA first go, all credit to the goold old BMA crew
No discernible LBA connection in this post: my apologies!
