The evacuation of concourse A at DEN this past Friday brought up a question in my mind regarding the layout, as I recall it, of the security checkpoint that had the breach:
The checkpoint was apparently located near the walkway bridge that connects the terminal with concourse A. (Keep in mind that only concourse A was evacuated). However, once you're on concourse A, you can take the underground train to concourses B and C.
Was the thinking when they only evacuated concourse A that nobody would have had enough time to make it to the underground train to B and C? (I recall that only 10-odd people went through the device during the time the mag didn't have any power).
