sorry, it was Peter who cleared two aircraft to the same level. It was series of mistakes and wrongdoings from all sides (managment, Skyguide, etc..), but let's not forget why we are there...to enable safe, orderly and expeditious flow of traffic.... please don't understand this as bashing or ruining Peter's memory...but to make a muderer a hero, helps nobody and shows state of mind...he couldn't bring his family back, and just one name was added to total tally from the catastrophe...
If you don't know what exactly happended (which clearly you don't), then you should definitely refrain from writing stupid comments about the circumstances. The lack of knowledge/information is what lead some people to celebrate a murderer as a hero. You're just adding incentive for those people. Very sad and unnecessary.
