http://www.nzz.ch/2005/10/30/il/articleD9VFI.html Main points:
The one-man operation as applied in Zurich is not in accordance with safety requirements in Air Traffic Services. The organisation of ATC requires a backup for human failure.
Three managers, between 50 and 61 of age, one of them being the former manager of ATC Zurich, were found guilty for negligent behaviour resulting in the death of people and sentenced to 12 months suspended.
The Swiss one-man operation had been contested previous to the collision and had been suspended in Genève. In Zurich nothing had been changed despite repeated criticism, which the court noted as "industrial blindness".
The lack of information about the maintenance of communication lines was blamed to the project leader, who was on leave at the time of the collision but had failed to inform the adjacent centres; The 64 years old pensioned project leader was sentenced to a fine of 13.500 Swiss Franks. The technician on duty at the night of the collision was acquitted.
Also acquitted was a supervisor, a system manager and the controller who had taken a rest. The latter was acquitted thanks to a juridical contradiction. On the one hand he was charged to be negligent in obtaining information about his watch but on the other hand he had taken his rest despite this knowledge and in agreement with his (murdered) colleague.
Skyguide is discussing with their convicted staff whether to lodge an appeal. Two of the convicted staff are still employed, but not in their original function. The court called the convicted staff members to accept their conviction in the interest of all parties involved.
