You absolutely have no idea. Read the findings from the Lion air crash. Then read about what the ETH pilot said to the control tower. It's a flaw in the system. A senior pilot, 8K hours on him, doesn't arbitrarily drop a plane.

While I agree with everyone you said, 8k isn't that many hours for a Captain, much less a senior pilot at a national carrier.
