If you ever saw the movie Total Recall, you've seen airport security as it will be. As The Governator, Arnold Schwarzenegger, walks through a tunnel an X-ray machine projects his skeletal frame onto a wide screen in an nearby control room.Returning to the USA last week from Mexico, our plane landed in San Francisco, where we would go through customs (and security). In Mexico, the security at the airport could best be described as perfunctory. Yeah, I set off the metal detector as I always do, but instead of the frisking, questions and patdown, I just got a quick pass with wand. No liquids out, no computer out, no shoes or belt or jacket off. It was almost like the old days.
In San Francisco, going through the gauntlet to get back to the US, I was placed in an entirely new (to me) machine. It's an extremely sleek and futuristic looking booth. I told my traveling partners it looked like something the Nazis might have dreamed up in 2000, if they'd been around. This booth smells you!
You step inside. The doors silently slide closed and the machine begins blowing air around you and directing jets of air at spots on your body. It stops, analyzes the air for explosive residue, and flashes a little green light to say you can proceed. I was blown by the TSA.
