But let's wait the report to be published.
I am not sure there will be a report published by BEA. This could be just normal ops, like electing to return afer a cracked windscreen due hail ?
It is the combination of the airline involved, the weather avoidance and the route, that makes it headlines news. It might be nothing more.
If on the other hand you have a crew blindly following a SID through a Cb , then you migh have a problem worth investigating, . But for the moment we do not know if that is thecase or not.
