As most of you know, I no longer make it a habit to frequent my local aviation-related establishments, as I have no use for them as long as the current scope & grope regime is in place. However, despite my protestations to the contrary that she take the train, my sister flew down to Houston to visit my parents (who snowbird) and I for a post-Christmas visit. As I work very close to Hobby, and her flight got in at 5PM, I volunteered to go and pick her up. Getting there rather early and a mob scene at the arrivals pick-up area, I proceeded to park and stroll inside to the checkpoint exit, to observe the Dog and Pony show for entertainment purposes. Hobby's checkpoints employ a mix of WTMD and MMW machines. Over the 30 minutes I was watching, the MMW took an average of 15 seconds to clear, with a FAR of about 10%. Interesting, for each FAR, they sent the person BACK through the MMW, and then on their way - I saw only 5 cursory localized pat-downs after a second scan. The WTMD, of course, took on average 7-8 seconds to clear, and since they have only the one checkpoint, they used the MMW in "Waves", that is, they'd use the MMW, the line would back into the terminal, they'd go back to WTMD until the line got down to 2 wrap-arounds, turn the MMW back on, the line would back into the terminal, ad infinitum. Anyway, from my exit late vantage point, I had not one, but TWO, travelers pulling roll-aboards go up the exit lane, wake up the exit lane drone to show him some ID, have the ID checked by a supervisor, sign a paper, and roll right through, no screening whatsoever. Neither individual was in any kind of uniform, so it wasn't crew access. Any ideas?
