In the Inmarsat data of MH370, there are handshakes (BTO) with time (UTC) at: 19:41, 20:41, 21:41, 22:41, 00:11,00:19. Normally it pinged every hour, but why the 2nd to last happened at 00.11 that was 1.5 hour after the previous one? The last one happened at 00:19 is for what reason?

Also can ping be stopped manually, e.g. by turning off the power, then there will be no ping?

This was explained back in 2014 when the data was released. It is consistent with a loss of power due to fuel exhaustion, followed by battery power restoring communication.

  • $\begingroup$ I can not find the 47 page report. Please explain more on why the 2nd to last happened at 00.11 that was 1.5 hour after the previous one. The final one was considered as power failure, which I think is inconclusive because if power was shut down intentionally, it would also have the same result. $\endgroup$ – User1006 May 27 at 15:24
  • $\begingroup$ Why after 22:41, it took 1.5 hour to next ping at 00:11, while all previous occur in 1 hour? $\endgroup$ – User1006 May 27 at 20:06
  • $\begingroup$ To conclude power failure happened simply from final logon request is inconclusive because manually turning off power would also get battery takes over -> reboot -> login request $\endgroup$ – User1006 May 27 at 22:38
  • $\begingroup$ That is all I need to know. There is a theory of MH370 being hijacked rather than crashed into the Indian Ocean. Thanks any way. $\endgroup$ – User1006 May 28 at 15:20
