BBC reporting:
David Gleave, an air accident investigator whose specialty is pilot suicides, says the aviation industry needs to start looking at the psychological profiles of pilots. "We may find that this pilot had various stresses that may have led to some form of relatively irrational behaviour. It could be a vast amount of debt taken out for pilot training, it could be family matters, it could be religious matters. There's all sorts of areas that the psychological specialist will start to look at during the investigation but I certainly think that it's going to be reviewed fairly quickly."
