Cheers for the amendments gents.
12:41am - MH370 leaves Kuala Lumpur for Beijing.
01:07am - ACARS shut off: likely deliberate.
01:21am - Transponder shut off: likely deliberate.
01:22am - MH370 disappears from Subang Air Traffic Control.
***01:22am+ - Timeline murky. At some point MH370 "turns back" westward across the Malay Peninsula, then turns northwest into the Straits of Malacca, and continues flying until it leaves military primary radar coverage. Aircraft movement during this period is considered deliberate.
02.40am - "Contact lost" reported to Malaysian airlines.
***06:30am - Scheduled landing in Beijing, MH370 nowhere to be found.
08:11am - Satellite "pings" MH370. Location impossible to pinpoint. Vague window of "a northern corridor stretching approximately from the border of Kazakhstan and Turkmenistan to southern Thailand, or a southern corridor stretching from Indonesia to the southern Indian Ocean"
That was just the time when the airline was informed. The last radio contact was either with Subang ATC around 1:20 am or with another 777 nearby at 1:30, if you believe the pilot (or did I miss the official confirmation for that account?).
12:41am MH370 departs Kuala Lumpur International Airport
01:07am Last ACARS data transmitted
01:20am (approx.) Last contact between MH370 and Subang Air Traffic Control, who are handing over to Ho Chi Minh City ATC (the last radio transmission heard from the aircraft was "Okay, good night", it is unknown who said it).
01:21am Transponder signal is lost near Waypoint IGARI (N6.92 E103.58). MH370 disappears from civilian radar.
At the same time the malaysian military's primary radar starts tracking an unidentified radar contact moving from IGARI towards VAMPI in the west.
(
01:30am Since the aircraft fails to contact Ho Chi Minh City ATC and doesn't respond to their calls, the pilot of another Boeing 777 only 30 minutes ahead of MH370 is asked to contact the plane via radio on an emergency frequency. The pilot reports to have heard someone mumbling in reply (no Mayday call).*
UNCONFIRMED*)
02:15am Last confirmed (malaysian) radar contact about 200nm northwest of Penang in the Andaman Sea.

07:24am Malaysia Airlines confirms to the public that contact has been lost and SAR operations have begun.
