After this Position Report was sent there were no further ACARS transmissions from the aircraft.


01:07:48 MYT

Last DATA-2 ACARS Message received at the GES. No further SATCOM Data-2 ACARS messages or acknowledgements were received at the GES for the remainder of the flight.

01:11:59 MYT

MH370 was tracked by HCM ACC Secondary Radar; and Automatic Dependent Surveillance- Broadcast (ADS-B); as it was heading for waypoint IGARI.


01:19:26 MYT

MH370 was approaching the Transfer of Control Point between KL ACC and HCM ACC (waypoint IGARI) so Kuala Lumpur air traffic control contacted MH370 at 01:19:26 MYT and instructed MH370 to contact Ho Chi Minh air traffic control on the VHF radio frequency 120.9 MHz.

At 01:19:30 MYT MH370 acknowledged with “Good night Malaysian Three Seven Zero”.

This was the last recorded radio transmission from MH370.

The words “Good Night Malaysian Three Seven Zero” were spoken by the Pilot-in-Command, Captain Zaharie Shah. However, he did not readback the assigned frequency, which was inconsistent with radio-telephony procedures.


01:20:31 MYT

Radar recording showed that MH370 passed through waypoint IGARI at 1720:31 UTC (0120:31 MYT).

This was earlier than would be expected by Ho Chi Minh ACC (0122 MYT), and sooner than predicted by a flight reconstruction in a B777 simulator (0121 MYT).


01:20:36 MYT

The Mode S symbol of MH370 dropped off from radar display at 1720:36 UTC (0120:36 MYT).


01:20:45 MYT

Ho Chi Minh Air Traffic Services radar data recorded the “blip” from MH370 from both SSR and ADS-B radar position symbols disappeared from the radar display at 01:20:45 MYT.


01:21:13 MYT

The radar position symbol of MH370 disappeared at 1721:13 UTC (0121:13 MYT). The KL ACC radar and the Bangkok radar both recorded the target drop at 1721:13 UTC (0121:13 MYT).

MH370 was 3.2 nm beyond waypoint IGARI when the SSR radar position symbol of MH370 dropped off from ATC radar display.

Military radar (Primary Radar) showed the radar return of MH370 turning right but shortly after, making a constant left turn to heading of 273°, flying parallel to Airway M765 to VKB (Kota Bharu).

KL ACC Radar also captured the disappearance of MH370 at 1721:13 UTC [0121:13 MYT] but this was not noticed by the Duty KL ACC Radar Controller.



01:22 MYT

MH370 was expected to arrive at waypoint IGARI at 0122 MYT (or one minute earlier, based on the reconstruction of the flight profile conducted on the B777 simulator).
