So to put this in its context as stated at the beginning of the film
we shouldn't concern ourselves with a controller making a mistake because its justified under the circumstances (busiest day, at capacity 15 aircraft to look after, alone etc. etc.) because its ok to chuck the safety imlications aside, its not worth reporting.
I would have thought professionals concerned with safety would have submitted a report to ensure the next mistake isn't a more catastrophic one.
I am horrified at rhe unprofessional responses over the radio and on here.
