Shocked by the statement that the co-pilot is to blame.
On the CVR he has apparently normal breathing to the end, I don't see that means anything at all.
It shifts the spotlight from the reinforced locked door policy, and for there not being 2 people in the cockpit at all times. And wraps up the case very quickly in light of numerous recent unexplained incidents.
I see no motive or evidence here for the co-pilot taking the blame.
Maybe he had a stroke, heart attack, took some drugs that knocked him out, or a part of the ceiling panel dropped on his head.
How can his breathing be normal if he is committing suicide and crashing a plane ?
