In its 87-page final report into the tragedy, the French crash investigation agency, the Bureau d'Enquêtes et d'Analyses (BEA), found that they could have done nothing to stop Lubitz.

"No action could have been taken by the authorities and/or his employer to prevent him from flying that day, because they were informed by neither the co-pilot himself, nor by anyone else, such as a physician, a colleague or family member," it said.

The BEA's report revealed that a private doctor had recommended Lubitz be admitted to a psychiatric hospital a fortnight before the crash.

So it seems from this report that it was his personal physician, rather than a corporate Occupational Health doctor, who had seen him.

I'm not sure my own doctor in UK would even know what I do for a living. I've certainly never told him, and I don't know where he would have found out the information otherwise. I'm just a patient with an NHS number, an address and a medical history going back virtually to birth.
