Pilots can be their own worst enemy

It would seem that just about everything we do in commercial aviation is associated with a verified procedure or checklist – lines drawn in the sand that may be bent only when the pilot-in-command has a very real reason to do so. Rather than being unduly restrictive, such guidelines provide a framework around which routine operations are built, enhancing safety through their predictability. But, as always, there is the human variable and for this there is no preflight checklist where one size fits all.
