FWIW.... 'not much' I hear you say.
I think OVER reliance on checklists is what causes stuff like this to happen.
Folk have it drummed into them that they MUST follow the C/L at all costs.
This leads them to think that as long as the DO follow the C/L ,that all will be well.
People need, ABOVE ALL ELSE, to think-and to be aware of their surroundings.
Also to realise that Airmen, above all else, rely on Airmanship and NOT checklists or slavish adherence to SOP's (invaluable tho' they certainly are) to keep themselves alive!
