N380UA:
The letter written on 7th May 2004 by UVEK/BFU to the German Air Accident Investigation Bureau admits that two (out of three) systemic faults had contributed to the mid-air collision over Ueberlingen.
These two systemic faults are clearly identifed as being in Skyguide's court.
Thus - as opposed to the innocence of Peter Nielsen - who was simply doing his job - there is no innocence on the part of Skyguide, its management and its political masters.
