I believe that the fuselage (being extremely long) flexes and twists when up elevator is commanded for the flare. This is resulting in unpredicted behaviour during the flare - especially with crosswind. Couple this with the high ground speed incurred because of JNB's elevation and the large amount of thermal activity, then it is causing problems in retaining the aiming point and getting the flare right. There have been many very deep landings at JNB (in both the horizontal and vertical sense) and frequent go-arounds.
