T-Ray Camera Sees Through Clothes, Preserves Privacy 315
Quite a few readers are sending in stories about ThruVision's products, slated to be demonstrated in Britain next week, that are claimed to use Terahertz radiation ("T-rays") to detect foreign objects under clothing, without revealing body details, from a distance of 25 meters and while the subject is in motion. T-rays lie on the electromagnetic spectrum between infrared and microwaves, and are the subject of lively research efforts worldwide. ThruVision says it developed its products in cooperation with the European Space Agency.

20 Years ago I went on a plane with DYNAMITE baby!
I was a kid, and all I wanted to do was to get some M80's and M160's back to my school for some good harmless fun. I stuck it in my desktop computer (no really), in a bag between the hard drives and the floppy disk where there was still 2x5 1/4 bays.
I figured what is the worst they could do to a 12 year old?
Of course.. now as an adult I realize that putting about 2 dozen firecrackers into the overhead compartment was just a little unwise.

The argument is that the liquids they are afraid of are volatile and hard to contain in cans, and thus you would see condensation on the inside of the bag.

I'd say GP has a point -- the idea that the bag is there so they can see condensation sounds bogus.
According to the TSA's website, the reason for the bag is to impose an overall limit on the amount of liquid carried by each passenger. (Which as near as anyone seems able to tell is also silly, but that's another matter...)

That being said, suffice it to say that I managed to get a can of lighter fluid on a plane, even after they put the restrictions on liquids in place.

Actually there is a good reason for the plastic bag.
The plastic bag is used as a quick way to confirm that the passenger is bringing on less than a certain total volume of liquids. You are allowed a single one quart bag, therefore it is obvious at a glance that you are carrying on considerably less than a quart of liquids or gel.
It's not a foolproof way to keep terrorists from assembling a liquid bomb on board. It just means you need a larger n

I don't at all get the obsession with body-shape in American culture. Those images give you an idea comparable to what you get on any beach, besides, it's just a human body, most of them are quite similar, there is some minor variations, but really, it's not -that- interesting. People who -do- want to look at nude girls (or boys) have a limitless supply already, and that is perfectly fine.
It bothers me a lot more that the idiots think they need to know every tiny thing you bring with you, be it a can of Coke, a tube of toothpaste or a key. I can live with the metal-detectors, though frankly I don't approve of even those.
As for the "airplane as missile" threat, that is trivially handled: Install a locked, secure, cockpit-door, end of story. It's not as if: "Fly the plane into that building, or I'll kill this passenger" will work. (the pilots would just refuse, it makes no sense to kill everyone, including that passenger to prevent the killing of a passenger)
Besides, I have the same ridicolous restrictions when flying on a 20-seat plane flying say Anda - Bergen, there isn't even a potential target within the RANGE of the airplane. If someone *does* take over the plane, best they could do would be killing everyone aboard, plus a single-digit count of people on the ground if they do their aiming well, frankly, this "threat" does not worry me much.
Frankly, if your goal in life is to manage to somehow kill 20 people, there are easier ways. Defending against them all ain't worth it, because any marginal increase in security is more than counterbalanced by MASSIVE losses of freedom.
I'd rather live free and have a 1:1million chance of dying as the result of a terrorist-attack, rather than live in a cage, checked every step of my travels, and have a 1:2million chance of dying as the result of a terrorist-attack, both risks are negligible anyway.
