end of the flight between 2 h 14 min 26 and 2 h 15 min 14
The 2:14:26 time was the aircraft / satellite handshake time of the last message transmitted and received in Paris. The 2:15:14 time was the latest time that the fault message believed to be in the system would have been sent and received.
There may have been other ACARS messages waiting for transmission, but we do not know. I suspect the actual impact time was seconds after the handshake time at 2:14:26.
