ACARS is what the article seems to be saying is how they know. Last ACARS transmission was 1:07 am. Any pilots here who know whether ACARS actually transmits FMS information?
Edit: And if the report is correct and ACARS sent the information all along, why in the world did it take them 10 DAYS to find this out?
