Rough and smooth
A packed Virgin 747-400 LAX to LHR corker some years ago in severe weather. She was late in and we sat there watching disembarkation. Many of the pax looked white and shaken and some had to be helped off. When we loaded further delay due to door locking problem. Captain and crew were great but warned it was going to be a rough ride back. We soon found out what it was like to be inside an electrical storm at night and what the word turbulence meant. Pax were crying. No hot food served, only drink. Everything shaking and rattling, little white bags everywhere, but we got through and there was very loud applause all round when we touched down. A great credit to plane and crew, all real aviation professionals.
Contrast - a magic carpet ride in a Thai Airbus A340 last year from BKK to LHR. Hardly a tremor on the whole flight and two seats all to myself. The stuff of dreams.
