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?

According to wikipedia ACARS can include FMS info. It is odd that this has taken 10 days and even now is kind of leaked by "an American official". You'd think they would have checked that stuff straight away and made it at least semi public so aircraft experts could check it out.
