It was when he was 21 and had just started that he had the “breakdown,” so that would have been in 2006 or so (he was 28 at the time he brought down the plane).
They retested him and readmitted him to the training.
That makes sense. As per usual, the details are all over the place and off the wall. Dates of leave for the depression are a turkey shoot. It’s a case of “pick one”.
Certainly appears he was in good shape to be able to pass the rigors of the German psych exam, reportedly the best in the business, as well as accumulated flight tests. He slipped through.
I think there must be something to the opinion that pilots don’t want to report depression, especially recurring depression due to the automatic removal from piloting. They may not even treat it, for fear of exposure. A catch 22, because no one wants them flying.
