Operator of MH370 / 9M-MRO
Declared the flight missing at 23:24 UTC while the SDU was still a live Inmarsat terminal.
MAS operated the KUL–PEK night service. Operations placed unanswered sat-phone calls at 18:39 and 23:13 UTC. The public missing statement came hours after radar loss and while handshakes continued — a GADSS-era lesson.
