Hardest landing (as a PAX) for me was a BA 757 into Manchester at night. Full on carrier landing, 2-3 overhead bins popped open, not much of a bounce but we hit VERY hard (experience 1,000+ flights as a PAX and PPL (A) own landings).
FO came on the intercom and said "Sorry about the rather firm landing, but those last 10 ft or so always take me by surprise...." Laugher and clapping all round. Plus he was standing at the front when we went out - respect earned and no one hurt.
