Failed handshake — terminal silent
01:15:56 UTC
The ground station interrogates 9M-MRO and receives no response. The aircraft is no longer a live terminal.
At 01:15:56 UTC Inmarsat’s ground station sent a log-on interrogation. There was no reply. Combined with the 00:19 log-on, this brackets the end of electrical life of the SATCOM terminal. It does not by itself timestamp impact; it timestamps the end of the recorded signalling.
