the atmosphere in the pilots' cabin was quite cheerful and relaxed, talks on private matters and on general matters, until the last seconds of the flight when the hell so to say suddenly broke out.
Again a clear proof of lack of CRM skills.
Did they ever hear of "sterile cockpit"?
Alice, could you confirm the rumour, from the other forums,
that a retired pilot, who was one of the first on the scene
after the accident reported fifth body in the cockpit?
It would fit with the information about at least two persons
visiting the cockpit.
