What we know* timeline
(*or at least have a separate "unidentified official" verification on from a reputable source)
-
1:07 - ACARS last transmission (thru VHF) which apparently includes notation of a WP change having been entered into system since last scheduled report at 12:37
-
1:11 - INMARSAT ping would have been received, as apparently Boeing's AHM report attempted to automatically transmit (thru Satellite?)
-
1:19 - 'Alright, Good Night' at handover (supposedly by co-pilot)
-
1:22 - Transponder goes off
(note: those previous two might be reversed, we have multiple sources seemingly confirming both possibilities. One happened at 1:19, one at 1:22 though. I'm putting them in this order mainly because...)
-
1:22 - Plane goes out of range/black from Thailand Radar (likely from the transponder going black and not the plane going out of range)
-
1:28 - Unidentified plane shows up on Thailand Radar roughly off the Kota Bharu, Malaysia coast (at Malaysia/Thailand border) and this apparently shows plane crossing the Peninsula to the Straights of Malacca (unknown endtime for this path)
-
somewhere between 1:15-1:30 - Vietnam sees plane turn around.
(note: they have not told us a specific time of turn or if they know this because of a Military or ATC radar hit, but they told Malaysia they 'watched plane turn around' sometime shortly after contact was lost)
- roughly 1:30-forward, Vietnam is "frantically" trying to contact the plane
-
1:37 - ACARS misses scheduled transmission
-
1:30-1:45 - at minimum 11 eye witness reports from around and past the Kota Bharu, Malaysia/Thailand border areas (including one saying 'plane descending fast' like one of the later radar hits indicates)
-
2:11 - INMARSAT ping would have been received, as apparently Boeing's AHM report attempted to automatically transmit (thru Satellite)
-
between 1:30-2:40 - Malaysian Military and Civilian radar picks up an "unidentified" plane flying over peninsula (Daud says "this was corroborated by civilian radar" in the March 9th press conference). Those include a couple radar WP hits we have specifically been told about* (and who knows how many that haven't been provided/leaked):
... VAMPI
... GIVAL
... IGREX
(note: we are not sure of the timing of the radar hits, and there is very contradictory evidence here. The most recent seemingly-official time is 2:15 for the last hit. Which hit that was, we don't know for sure)
post 2:15/or/2:40 apparent absolute
complete blackout of plane (except...)
-
3:11 - INMARSAT ping received, as apparently Boeing's AHM report attempted to automatically transmit (thru Satellite)
-
4:11 - INMARSAT ping received, as apparently Boeing's AHM report attempted to automatically transmit (thru Satellite)
-
5:11 - INMARSAT ping received, as apparently Boeing's AHM report attempted to automatically transmit (thru Satellite)
-
6:11 - INMARSAT ping received, as apparently Boeing's AHM report attempted to automatically transmit (thru Satellite)
-
7:11 - INMARSAT ping received, as apparently Boeing's AHM report attempted to automatically transmit (thru Satellite) near 40 Degree line
-
7:24 - Statement released by Malaysian Officials saying contact lost at 2:40 and SAR efforts are underway
-
8:11 - INMARSAT ping received, as apparently Boeing's AHM report attempted to automatically transmit (thru Satellite) (thru Satellite) on 40 Degree line
*those way-points on map
(Note on map: the Thailand radar data, as we understand it, indicates a straight path from IGARI to VAMPI is not possible, so there are more unknown/unreleased turns in there somewhere. Please do not read that map as a 'straight flight' from WP to WP; it was not a straight path over the peninsula, in the very least)
Anyone have any other times to add and/or corrections? Would like to keep this as updated and accurate as possible for all, and any input is welcome! (just, want to keep it to things cross verified, so please keep that in mind if suggesting other times - that is why things like the possible post-1:30 JapanBoundFlight/MH88 call is not included here)
