We arrived very early for our flight, fearing long waits for our turn at being groped. But in fact there were no queues at the security screening, and more TSA people than I have ever seen in one place.
At our concourse (“D”) they had both metal detectors and what I think were backscatter machines right next to each other. Most people were being run through the metal detector, a few through the scanners. None of us got picked for it; we all went through the metal detector and that was that. (Once again my metal valve didn't set it off.)
Then we spent a very long time in the airport waiting for our flight.
