I guess as someone who never makes mistakes, you never amaze yourself!
Very defensive retort Sooty. Yes, I do amaze myself at times. Luckily not whilst in command of an airliner full of passengers. This could have been catastrophic. They are supposed to be highly trained professionals and whilst mistakes can occur due to sometimes understandable (though not acceptable) mitigating circumstances, on this occasion they must have been mightily distracted on this clear day with the actual runway clearly visible next to them. That they went as far as commencing the roll on a clearly identifyable taxiway is defenseless. Would you have felt the same if it had been catastrophic and your loved ones were on board?
