a few points- firstly, it was a 737-400, not an airbus. Secondly, apparently Hyd System A lost pressure after they were already fully configured - gear down, Flap30 - at around about 1000'radio.
Therefore everybody involved had very little notice as to what was going on - and i imagine the guys were pretty busy troubleshooting the problem. Give 'em a break! Okay? Or how about job well done guys!
