I'll trade a naked image of my fat body for keeping my shoes on any day of the week.

What about letting your money, ID, and other valuable out of your control where someone may steal them? That's part of the ride too.

A Swiss company has introduced a line on underwear that is said to be "radiation proof" for those concerned about cell-phone radiation.

"Developed by Swiss designers, the Slipways underwear range is made with threads of silver to help fend off harmful from devices such as mobile phones.
The Slipways briefs are said to be so effective that any phone calls made in the confines of the underwear will completely fail to connect, though why anybody would try to make a phone call from within a pair of Swiss briefs is beyond us."

If they catch on as a scan blocker for specific body parts will be interesting to see TSA's response.....

He just doesn't know the right people in Switzerland. ;)

They'll just make you take them off. (I wish I could put the winking smilie here to show you I'm kidding, but sadly, I'm not. Where's the weary-sigh smilie?)

From everything I've read so far, stepping into the strip-search machine does not exempt you from the shoe carnival. In fact, the sample MMW images we've been seeing don't reveal very much below the ankles. Worse yet, walking barefoot from the beginning of the x-ray belt, into and through the nude-o-scope, and then back over to the pick-up area is an even longer path on the filthy floor. And we still haven't been told what the SOP is for toddlers and infants. The MMW insanity must be stopped!

One of the bloggers over at PV said if they can stand and raise their hands, they can stand in the strip searcher. :td:

If the parent doesn't like that option, like their parents, they too can be felt up. :td:

TSA is doing more to terrorize aviation than Osama ever could. :mad: :td:

You will be disappointed.

You still have to remove your shoes even while being peered at by some TSA pervert hidden away from public view.

You might not be too far from the truth. Granted this article does talk about detecting cracks in concrete, but it does give you an idea of what the resolution is.

From the article

The results of an experiment are shown in Fig. 5. A 0.06-mm-wide slit was created by abutting two plates of aluminum, which has a permittivity similar to that of concrete, and the intensity distribution of the reflection was measured using the millimeter-wave transmitter/receiver. The wavelength of the millimeter-waves used was 4 mm, and the transmitter/receiver was positioned 10 mm from the aluminum plates. In the resulting graph and image, we can recognize the 0.06-mm slit as a blurred 7-mm wide valley in the reflection.
By using interpolation techniques and image processing they can, indeed get very high resolution pictures with MMW.

Some more interesting stuff from 2001 where the FAA doesn't like it.

For the prototype cylindrical system, which operates from 26 to 30 GHz, a bandwidth of 4 GHz is sufficient for good depth of focus. Lateral resolution is approximately 1.0 cm, whereas the depth resolution is 3.75 cm.

"Despite the overwhelming success of results from the system, public acceptance of this type of imaging may be a significant hurdle to implementation of this technology," says McMakin, program manager. "Although the images are low resolution by optical standards, they do reveal anatomical characteristics of the person being screened," he says. At present, the US Federal Aviation Authority is opposed to presenting this type of image directly to an operator, and PNNL is investigating pattern-recognition and image-segmentation techniques to eliminate operator intervention.

Move the operating frequency to 94GHZ and you lower the resolution to around 3mm (2.54mm = 0.1 inch) without image processing to improve resolution. Near photographic albeit fuzzy quality.

I had the opportunity to refuse the MMW today at Reagan National.

Them: "Sir, you've been selected for secondary screening. Please step in here."

Me: "No."

OMG!!!...

You would've thought I had dynamite strapped to my forehead.

"REFUSAL!!! REFUSAL!!! PAT DOWN! NOW!!! REFUSAL!!!"

I made a LOT of friends in a very short period of time.

Good for you. How did you win the opportunity for a secondary screening? Did you beep in the WTMD?

Good on you! ^

Did you get to explain to other pax or anyone at the checkpoint why you told them to go to hell?

I can so picture this, and it cracked me up.

I didn't beep the metal detector.

I was surprised that there were no signs informing that the MMW was optional. Just "You've been selected... step in here."

Thanks to Flyertalk, I know to 'Just Say No.'
