Did you notice how it jarred the right flap section? They kind of move anyway, but generally not that much. I saw a Luftansa A-340 hit so hard that it actually bounced back up about 50 feet. I thought they were going off the runway, but they managed to regain control. Looks like this 747 pilot realized his late flare and tried to fix it, but too late. I'm sure glad I've never done anything like that; not even twice! Ok, Ok, my third landing in the 88 was so hard that I think it may have changed the orbit of the earth.

P.S. LOT landing: Some of the later articles are now contradicting the initial ones. Now they are saying the crew realized they were going to land gear up after reaching Warsaw and making several attempts to extend the gear. Although it's still a mystery as to why the Alt Gear Ext system failed, this account would make much more sense.
