I'm back and severely jet-lagged. So it'll be a couple of days before I'm back up to speed with what's been happening. But yours truly got his first full-body scan at O'Hare on this past trip. Yippee!
I couldn't figure out if it was the X-ray backscattering or the millimeter wave technology. I was about to ask one of the TSA's officer what it was, but they were all rather busy at that time, and I was already "loitering" about the area for a few minutes. After giving it a thought, I decided not to risk raising suspicion about being too curious about the scanning technology and left.
Anyway, if anyone wants to look at the issue surrounding the millimeter wave technology, check out an earlier blog entry. Ars Technica has a good article covering the x-ray backscattering technology.
