Fog in the Head

At dawn on September 30, 2012, a Cessna 414 with 8 people on board took off from Innsbruck towards Valencia/Spain. Eight minutes after takeoff, only two of the occupants were still alive. The plane crashed near the site of Ellbögen, Austria.
Hans-Peter Zimmermann reproduces the authorities' investigation report and provides a possible explanation for the pilot's unusual behavior with his knowledge of psychopathology.
