Yeah, the American anti-intellectualism is ridiculous, but fortunately is uniquely American. India, Europe, and Asia rightly prizes intelligence.

In America, it's cool to be smart only to the extent it can make you MONEY.


Well, his name is Jigme Wangchuck (probably royally misspelled). I don't know what he is, but I know he is basically the head of the gov't of Bhutan.

And, in most places, I'd assume its cool to be smart because it makes you money. In most cultures, money is king. Its simple math.
smart = money
money = the deluded sense that you will be insanely happy

Most people desire the deluded sense that they will be insanely happy, therefore by the transitive property of equality, most people desire to be smart. Of course, in America, we are anti-intellectual, so we can't do simple math :P

Lots of folks follow the money trail, it is a natural by-product of intelligent, creative people...;)

Yet was wondering what their reliability was, at least in regards to costs (hey, we are paying for these, after all). Are they based on currently implemented technology (eg: hospitals, industrial, etc), easily maintained and/or repaired, are they modularized for servicing back at the plant, etc?

Are there any concerns that we're going to start seeing these out-of-service for use-based maintenance, field-calibration, repair, etc? Has the TSA indicated what they're going to do with the WTMD (leave them at the airport storage) in case there's a strategic need to over-populate the lanes, etc?

The WTMDs appears to be (technologically) simple (including field calibration by the TSOs), and the reports on the puffers speak for themselves. Thoughts on the operation impact of AIT reliability and predictability?

I have been told by another FTer that the medical physics lists are highly concerned that not only are there no maintenance services, but TSA does not do daily/weekly/monthly output checks (to determine the radiation emission levels), or calibration checks. If the machine were to malfunction it may not be apparent.

TSOs using these things: you seen any calibration checks/operational checks? If so, how frequent?

I remember that well. It was a big deal back then. The credibility of the source was highly disputed, if I can remember correctly

I have not seen the info on the maintenance other than to say that it is performed on 90 day intervals buy the OEM. We have had a MMW machine in DEN for over 2 years and it has performed remarkably well and has good "up time."
Most of the equipment that is bought has a one year warranty is supported for that whole year by the maker. In older equipment it is bid out to maintenance companies like Siemens.
The big players in the arena are Morpho detection, GE, Smiths Detection, Siemens and L3.

I believe that the possible maintenance issues brought up by the engineer that were referenced earlier were on Backscatter machines

What a huge waste of money :td: Just wait until the next "threat" appears :rolleyes:

Thanks for the empirical data.

Any concerns by the operators, say noises, screen quality changing, etc?

Having seen previous all-in simple-tech to high-tech transitions go bad, and all operations coming to a halt (and people screaming where's the old stuff). Just wondering what the strategic process is to ensure there's enough processing capability to deal with these AITs, when they start to get flaky.
