On 1 July 2002, Bashkirian Airlines Flight 2937 collides with DHL Flight 611 in German airspace near Überlingen. Flight 2937 is destroyed instantly, and the DHL cargo aircraft crashes shortly afterwards, killing all 71 people on board the two aircraft. The crew of Flight 611 followed the on-board traffic collision avoidance system (TCAS) instructions to initiate a descent. However, the crew of Flight 2937 followed the instructions of the air traffic controller instead of their TCAS and initiated a descent as well. Only one air traffic controller was on duty for that block of airspace at the time of the collision—his colleague, who was also meant to be on duty, was resting instead.
