It's too long ago to be the same aircraft I imagine but I did see a very hard A320 landing by Thomas Cook a while back at Manchester. I did post it on PPRUNE at the time and asked the question if the plane is designed to take such a hard landing. It literally dropped the last (guesssing now) 20 feet or so and I cringed when I saw it. What astonished me was how high it bounced, almost back to the same level. It then seemed to float for a few seconds before full power kicked in and up he went. Compared to the other approaches I saw during that 2 hour period it seemed very lively on what was a relatively calm day. Unfortunately I'm not an airline pilot (red/green colour defect) so I'm not totally qualified to comment although I studied mech eng at uni many moons ago and have a reasonable degree of understanding about
structures.
