Unless I am misremembering, they had what they thought was a pretty firm link between the suicide-by-piloting crash in Europe and a pilot’s relationship/divorce.
I mean, “intentional pilot crashing” is probably not in the top ten list of causes of air fatalities, but I wonder if they should have an additional level of screening because of the possibility of job stresses and responsibilities clashing with the slings and arrows of outrageous fortune.
