I didn't want to participate in the rather ghoulish and idiotic mass of speculations by an awful number of self-appointed armchair accident investigation experts but as Danny changed the rules, here is some interesting factual information given by the French France2 channel.
Somehow, they managed to get the ACARS summary print-outs and had someone very briefly comment on them.
Here is how to get it :
france2.fr
then click on the "INFO" tab
then on the very small "JT" tab underneath (meaning journal televise)
then chose the 20 H - that's the eight o'clock news.
The two pages are quite clearly readable on time frames 5.50 and 6.45.and you don't need to understand French !
But they don't seem to have the complete list of faults.
What these messages show, however, is that events happened quickly, so people who know the 330 can now have a better picture of the events preceding the disappearance of flight 447.
