This episode is one that needs very close examination to see where the error occurred - and the authorities are treating it with the gravity required. No-one should need reminding, that it would have only needed ONE other aircraft to turn into the taxiway, at the wrong moment, for us to be reading about another major KLM disaster today. I'm with blue heaven, what were ATC doing? - besides adopting a less-than-professional attitude to aircraft control and movement??
