Ushuaia, I have no first hand knowledge of this event, but there is a lot of reading between the lines in the media which are often rather reserved in this. Especially the fact that the pilot made contact with loved ones before the presumably fatal flight.
As an aside - One media reported that the pilot appeared normal and relaxed prior to departure so it was unlikely anything premeditated. That may be true, but I offer the following. Many years ago now, I got to know and shared accommodation with a man who was rather withdrawn and not overly friendly. Seven months later he reappeared and was very friendly and relaxed. A different man. Refreshed after the break, I thought.
One week later he hanged himself.
