wallybird - I would ask you to carefully read both the current and old threads on this topic? Your fixation on 'thunderstorms' is out of place based on what we are told by BEA. There is also no firm 'evidence' of any 'thunderstorms' on their route.
There is no evidence that they 'penetrated' or flew near a 'thunderstorm'.
It is shown (in the reports) that their 'choice' to deviate to the west proved to be a better one than other aircraft which went to the east.
We do need more from BEA (hopefully 'at the end of the month') to tell us what radio calls and conversations actually took place on the flight deck. We just do not know enough at the moment.
