Hi,
The final report will be certainly interesting (more than about thirty days to wait if the schedule of the BEA is respected)
It certainly will conclude with recommendations to avoid such accidents in the future
The trial has come (when ?) will be equally interesting .. but will concentrate more on what could possibly be done before the accident to prevent such a tragedy
The BEA will say what to do .. the trial will probably tell what it should have been done before and why
