The aircraft passed the last set of touchdown zone markers at around 0:36 whilst still a good few feet in the air. I am willing to bet that some carriers would have continued with the landing with some 5-6000ft still available ahead but in BA the rules are very clear - no landing in the touchdown zone and it is either a go-around or tea and biscuits.
I believe the same is true about achieving a stable approach by 1000ft. In fact rumour has it that a flight recently appeared in BA's monthly safety brief which wasn't stable by 1000ft and didn't go around. This particular flight was "only" stable by 950ft!!
