Translations of BEA reports
The english translations of the original French BEA reports must be treated with caution. The BEA clearly states that the authoritative version is the original French copy.
That said it is interesting that the Capt was present for the bad weather briefing and then immediately left the cabin. IMHO seeing a solid wall of red on the weather radar at night is not boring and is not a trigger for taking a nap rest. Puzzling CRM.
