Anyone for comments on the possibility that post 02.14ZT ACARS mesages got lost because of range issues concerning INMARSAT (non) coverage of that specific part of the Atlantic (covered in previous post) ???
A (deleted) post states that the messages are transmitted with ECC codes. The use of forward-error correction in a two-way radio scheme strongly suggests to me that the engineers were concerned enough to have implemented an ACK/NACK request-retry scheme so that a message garbled by, for example, a nearby thunderstorm. would a re-transmitted.

The accident investigators will look into this carefully.
