1720:36 Mode S symbol of MH370 dropped off from radar display the last secondary radar position symbol of MH370 was recorded at 1721:13
1:21:04 MH370 was observed on the radar screen at KLATCC as it passed over waypoint IGARI.
1:21:13 The radar label for MH
370 disappeared from the radar screen at LUMPUR RADAR KLATCC. (Last secondary radar contact) Note: There was no ACARS message for transponder-off therefore, ACARS was off by 1:21:13.
1720:31 Radar recording showed that MH370 passed through waypoint IGARI
1:22 "aircaft suppose to pass IGARI at time two two" message was sent at 1950:16 based on the reconstruction of the flight on a simulator, the flight would be at IGARI one minute earlier than the original ETA of 1722
1:22 - Thai ATC Radar reported as losing the MH370 track at this time.
1:28 - Thai military radar tracked a plane flying in the direction opposite from the MH370 plane," back toward Kuala Lumpur. This track was intermittent but they did see the plane eventually turning right, (toward Butterworth)
1:30 - (estimated) Vietnam begins "frantically" trying to contact the plane - Vietnam sees plane turn around
1:33 - (estimated) 9MMRO passes over Kota Bharu (approximatly) nine witness reports from around Kota Bharu, (The first, and most dependable, described the plane descending as fast.)
1:37 - ACARS misses scheduled transmission (every half hour)

1:46 - HCM queried about MH370 again, stating that radar contact was established over IGARI but there was no verbal contact. Ho Chi Minh advised that the observed radar blip disappeared at waypoint BITOD.
1:46 - (estimated) Plane passes southernmost point of Thai airspace; at this point it can be expected to have turned toward waypoint MEKAR (groundspeed plots indicate as direct a route as possible to MEKAR)
1:50:27 KLATCC Affirm.... and confirm still negative contact with Malaysian Three Seven Zero
2:03:34 KLATCC Ah okay okay okay carry on I tell Singa Ho Chi Minh la we told the airline to contact. (1803 to 1805Z) no response from MH370 to communications attempts by the satellite (ACARS related)
