Typo was made during the conversion of UTC times. Meeting of SIA68 and MH320 occurred at 18:00UTC - 18:15UTC. MH320 dropped off of civilian radar at 17:22UTC.

Some have raised the statement that TCAS doesn’t work if the transponder is disabled… this is only partially correct. Other planes TCAS would NOT see MH370 at all. MH370 would not actively query other planes as it’s transponder is off HOWEVER it could still listen to any transponder output from other planes that are actively transmitting. SQ68 would have been actively transmitting while in-range of Subang ATC center.
