Please...if you can't multi-task, ya don't belong in a cockpit. Why don't we take care of ALL checklists and ALL duties before we ever move the aircraft? Because it's silly and inefficient. And I don't know about y'all but my head doesn't think that slowly.
They screwed up; they aren't the first and won't be the last...we'll always find another creative way to kill ourselves. Just don't let yourself be that idiot.
