D246,
You are correct it was the crews responsibility to check the switch positions and diagnose the problem etc and they should have done much better.
Yamaha,
Yes maybe the safety culture is an issue, although I don’t know anything about their operation so I cannot comment.
My point is that this happened to a crew with almost 10,000hrs on type and there is a history of 737 pressurisation/pneumatics panel errors from things like misconfiguring bleeds off take-offs to forgetting to reconfigure afterwards, misidentifying the cabin alt warning horn etc. This tells us that these panels/procedures can be confusing, even to experienced crew. The system is 40 years old and was Boeings first with a two man crew; these panels were previously managed by a flight engineer. 40 years and 121 lives down the road can we not make some improvements to the panels, like those I suggested above, to make the system more fool proof.
