Notes

1. The message content is intended for the Flight Management System (FMS) on MH370.
2. The content, however, was the flight planning information for a Malaysia Airlines flight MH371, as shown by the line:-
   <AIRCRAFTID>MAS371</AIRCRAFTID>
3. MH371 is the normal return flight from flight from Beijing (ZBAA) to Kuala Lumpur (WMKK) shown by the lines:-
   <DEPARTUREAERODROME>ZBAA</DEPARTUREAERODROME>
   <DESTINATIONAERODROME>WMKK</DESTINATIONAERODROME>
4. This message was transmitted at 2300:42 UTC (0700:42 MYT) which is later than the expected arrival time of MH370 at Beijing. But by this time Malaysia Airlines staff suspected that MH370 did not proceed through Vietnamese airspace - see the transcript of a conversation at 0520:16 MYT
5. One interpretation of this transmission is that Malaysia Airlines Operations uploaded flight plan information for MH371 to assist MH370 to return to Kuala Lumpur. Unfortunately, the initiative was unsuccessful.
