If I was in that aircraft and had a sudden loss of visual reference, the only real choice is to look across the cockpit at the AI on the left. It is indicating a right turn. Next to it is an ASI showing 30kt. The response would be to roll left, and lower the nose.
The aircraft is already in a left turn and doing 90kt. The extra roll and lowering of the nose will lead to a spiral dive. Adding to the confusion is a turn indicator showing no turn. The feeling from the seat of the pants, the wind noise increasing, and the instrument discrepancies will lead to a complete loss of situational awareness and eventually loss of control.
