On Mar 15th 2014 Malaysia's Prime Minister stated in a press conference: "based on new satellite communication we can say with a high degree of certainty that the Aircraft Communications Addressing and Reporting System (ACARS) was disabled just before the aircraft reached the east coast of peninsular Malaysia. Shortly afterwards, near the border between Malaysian and Vietnamese air traffic control, the aircraft’s transponder was switched off." Movements of the aircraft until the aircraft left Malaysia's primary radar coverage were consistent with deliberate action by someone on the aircraft. The primary radar target, so far believed but not confirmed to be MH-370, could today be identified as MH-370 with the help of new data received from the satellite data provider. The aircraft could have flown on for 7 hours, the last trace of the aircraft was identified at 08:11L (00:11Z Mar 8th). "Due to the type of satellite data we are unable to confirm the precise location of the plane when it last made contact with the satellite." However, the investigation was able to determine that the last communication was in one of two corridors: "the northern corridor stretching approximately from the border of Kazakhstan and Turkmenistan to northern Thailand or the southern corridor stretching approximately from Indonesia to Southern Indian Ocean." The investigation team is working to further refine the information. The search in the South China Sea and Gulf of Thailand has been ended. "In view of this latest development the Malaysian Authorities have refocussed their investigation into the crew and passengers on board. Despite media reports, that the plane was hijacked, I wish to be very clear we are still investigating all possibilities as to what caused MH-370 to deviate from its original flight path."
