Pilots are always concerned about apparent lowering of safety standards-anywhere. Ask yourself this question. Will "Andrew"'s revelations lead to an increase in separation and a subsequent reduction in movements at Heathrow (or any other busy airfield)? No, of course it won't.
"Andrew"'s concerns sound more like the anger of a man who is experiencing shock after his perceived career has been brought cruelly to an early end. He is hitting out at his former employer and colleagues. Perhaps in time, he will modify his opinions.
Pilots and the travelling public are maybe losing interest, as the incident referred to was not the first nor the last of its' kind and we all expect the safety precautions in place will prevent such an incident becoming a tragic accident. As the media have lost interest, then perhaps so should we.
