A horrible collision happened over Europe that resulted in the deaths of a group of school children from Russia, that weren't even supposed to be
there at that time.
There was a snafu with the flight they were scheduled for so they chartered a plane a few days later. There was construction going on at the ATC
centers in Sweden I believe it was, so they were passed to another controller, because three radios were being worked on. His partner went on break
leaving him watching two screens across the room from each other.
TCAS went off in both planes, telling the Russian plane to dive, the controller told them to climb, they listened to him, and collided with a DHL
After that crash ICAO and FAA passed rules that TCAS is the final ultimate authority. Regardless of the controller instructions, you listen to it.
Prior to that they were still in the "fact finding" stage with regards to that situation.
