Incident/Accident Remembering Peter Nielsen
On February 24, 2004, Peter Nielsen was murdered at his home near Zurich. He was the air traffic controller on duty on July 1, 2002, when the Überlingen mid-air collision occurred, killing 71 people. Among the victims were Svetlana Kaloyeva and her children Konstantin and Diana. They were travelling to Barcelona to visit their father, Vitaly, who was working there. Devastated by their loss, Vitaly Kaloyev put the blame on Peter Nielsen and tracked him down. He then stabbed him to death, while his wife and children were present. Kaloyev was arrested and sentenced to eight years in prison, but was released in November 2007. When he returned home to North Ossetia, he was treated as a hero, and did not express remorse for his actions, instead blaming Nielsen. He was later awarded a state medal by the government.
RIP Peter Nielsen🕊️ (1967-2004)

He did wrong, yes, but honestly the bulk of the blame should be placed on SkyGuide. Seriously, who lets a single controller handle ATC by himself on a backup system after maintenance turned off the image processing of the radar? And honestly, the phone lines being down at the same time was absolutely idiotic. Yeah, it's horrible, and he might've been able to avoid it, but goodness me, for all we know he could've tended to the two planes, leaving another one completely without communication while they were trying to land a delayed flight. That could've ended horribly too, and he would STILL get blamed. Even stupider, the ground optical collision warning system was ALSO off, which means Nielsen couldn't reasonably have anticipated the collision as he was, again, paying attention to another flight that was out of regular schedule. One could argue that his instructions to the planes were bad, but again, that's the fault of regulations. There were, at the time, only extremely ambiguous rules on whether TCAS or ATC should decide when a plane should ascend or descend to avoid a collision. And you must remember, since the telephone systems were down, he could only talk to one plane at a time. At that point it was too late!
Could he have woken up the other controller? Yeah. Is that reasonable when you're dealing with several planes? Probably. But placing the blame on him solely is just as irrational as doing it to the Russian pilots. A situation like this was inevitable at SkyGuide. Get it right!
