The DC-10, JA8546, cruised at {{convert|37000|ft|m|abbr=on}}. The TCAS on both aircraft functioned correctly, a “CLIMB” instruction was annunciated for Flight 907; however, the flight crew received contradicting instructions from the flight controller at the [[Tokyo Area Control Center]] in [[Tokorozawa]], [[Saitama Prefecture]]. Flight 907 followed an order to descend issued by the flight controller while Flight 958 descended as instructed by the TCAS, meaning that the planes remained on a collision course.
