If there was a tailstrike, as some reports say, the aircraft may have lost pitch control, not good if they then went around. The tailplane may have got damaged if the airplane was not on the runway.
Same if they did a wingtip strike and an aileron or winglet was damaged.
At some point in the ATC recording "height" is mentioned - uncommon altimeter setting procedure?
FDR and CVR should give answers soon.
