Malaysia Airlines Flight 370

==== Power interruption ====
The SATCOM link functioned normally from pre-flight (beginning at 00:00 MYT<!-- exactly -->) until it responded to a ground-to-air ACARS message with an acknowledge message at 01:07. At some time between 01:07 and 02:03, power was lost to the Satellite Data Unit (SDU). The final report stated "it is likely that the loss of communication prior to the diversion is due to the systems being manually turned off or power interrupted to them." Malaysian Prime Minister, Najib Razak, said it was clear that the radar transponders and the flight data transmission system were turned off deliberately by someone trying to hide the plane's position and heading.<ref>{{Cite web |last=Marks |first=Paul |date=15 March 2014 |title=Data transmission system on MH370 deliberately disabled |url=https://www.newscientist.com/article/dn25232-data-transmission-system-on-mh370-deliberately-disabled/ |url-status=live |archive-url=https://web.archive.org/web/20240115072035/https://www.newscientist.com/article/dn25232-data-transmission-system-on-mh370-deliberately-disabled/ |archive-date=15 January 2024 |access-date= |website=New Scientist}}</ref> At 02:25, the aircraft's SDU rebooted itself and sent a log-on request.<ref name=ATSB />{{rp|22}}<ref name="Ground log" />{{Rp|36–39}}
