I just mentioned the Hong Kong accident because I happened to start a Tech log thread on the ability of planes to take really hard landings. The story goes like this....
MD-11 coming into landing during a typhoon at HKG in 1999, approach gets a little destabilised at 500ft, but plane continues. At 70ft the auto thrust retarded to idle, aircraft enters the flare having lost a lot of airspeed.... despite the captain's best efforts the aircraft slams into the runway at over 1000fpm, wing snaps off as the landing gear collaspe, 3 people dead and aircraft completely destroyed.
