Incidents
On Wednesday, January 31, 2001, two Japan Airlines aircraft narrowly avoided a mid-air collision. The two airliners conflicted. Japan Airlines Flight 958, using a Douglas DC-10, descended according to traffic collision avoidance system (TCAS) instructions. A center employee told Japan Airlines Flight 907, using a Boeing 747-400, to descend while its TCAS told the pilots to climb.
