The guy had some kind of problem as he booked off his training for a period. Not a good sign and I am surprised the heads didn't red flag him and tell him to take a year off and come back when he is ready.
He sounds like a 'loner' living at home which is OK but can cut two ways introspectively imo. His FB site has some inferences .
I bet Germanwings is going to keep the two front seats warm at all times now.
There is no way they can test for substance abuse either I suppose.
