Which the pilot and co- don't know to trust as the altimeter and other instruments are giving false readings (listen to that recording, it's all due to the instruments being taped over by ground crew and the pilots missing it on pre-flight checks).

If you've determined that the stall warning is false I imagine it's hard then to back out and stop filtering that noise out; particularly when you're concentrating very hard on something else. Someone mentioned a case where the pilots crashed because they were attending to a landing gear problem and so missed the lack of fuel.

I wonder how men/women differ in these pressure situations too. IME women generally appear to handle multi-tasking and interrupts better than men do.
