The flight crews are still dealing with TSA induced bravo sierra long after getting through the milling checkpoint. The crew still has to contend with TSA "inspecting" aircraft they know very little about and make sure no damage has been done to important systems. This post-inspection inspection is a layer of real security as important as any other pre-departure checklist these unfortunate days. TSA will often hide make-believe "threat" items aboard aircraft to test the flight crew's vigilance. I have no problem with letting flight crew get through the line ahead of me. I figure my patience could well result in a timely departure into the blue far from the grasping blue below. I feel much safer aloft.
