The Captain's Response
I am definitely SLF.
The Captain re-entered the flightdeck in the middle of the developing situation. He had to gain situational awareness. He either gained it from the other pilots, in which case there would be a recording of what they thought was happening to the aircraft, or he gained it from his own senses i.e. whatever the instruments were then saying and what he could hear and feel.
It is fairly easy to assume the other pilots misinterpreting the information available to them and having formed an incorrect interpretation, continuing to apply the erroneous interpretion, disregarding evidence that conflicted with it. Unless the newcomer gained his understanding of the position by receiving an incorrect briefing, it is more difficult to accept that the Captain joined his fellow pilots' erroneous view of the situation without there being some pretty compelling, but ultimately wrong, data as to what the aircraft was doing.
