So I've only heard of it before until last month when I get to experience this. There's an old thread about this before but just a background: Coming to an Airport Near You: Full Body Scanners | Air Safety Week | Find Articles at BNET My impressions: - It takes longer than the regular scan. And the whole aiport screening process is already long enough. Before, you just strip yourself of anything that can go beep beep, and pass through a metal detector. Now, you still do the same stripping and walk into this space where you have to raise your arms and "pose" and wait while the one scanning you checks if you're ok or not. It takes a few seconds. So I'm wondering, if the scanners are indeed better at seeing every part of your body, then why the need to semi-strip like before? - I can imagine when people were afraid it was going to be invasive. I didn't feel at ease at all when I had to do that arm raising pose. I know the scannist (?) can see a lot. Even if they do say that images are deleted after and identity preserved, it still feels weird. Would this technology have any effect on your travel preferences?
