According to tweeting travelers , many backscatter and millimeter - wave AIT scanning machines at airports are not in use at all , makingopting out unimaginable . We’ve asked DHS / TSA for comment , but you’re able to help us confirm .

Not every airport in the country even has the “ Advanced Imaging Technology ” scanners installed . ( A Emily Price Post at FlyerTalk.com has anup - to - date list of airports with the machines , as well as specific terminal .

Gizmodo commenter “ The Dewd ” posted the above image showing Twitter updates that indicate that many of the machines are off , includingthis tweet from “ _ msw ” :
Through TSA checkpoint at SEA in 10 minutes flat . Many backscatter image scanner are off . No scan , no patdown . # SEA # optout # TSA
A report from the Associated Press , however , includes an imageshowing a woman in a body scanner at Seattle ’s SeaTac Airportdated today :

An airline passenger raise her arms as instructed in TSA ’s new full trunk electronic scanner at SeaTac Airport Wednesday break of the day , November 24 , 2010 . The bunch spirit level was normal , and there were no holdup . Peter Haley / Staff lensman
The presumption by some is that the TSA has deactivated the AIT machines in an drive to both increase throughput of traveller through the scanning process and to diffuse objection by the grassrootsNational Out - Out Daymovement .
But as the AP photo demonstrate , it ’s not always possible for a single passenger to see if an airdrome is using the machine at every terminal or not .

We will update this story as we get more information . If you are fly today , it might be useful to simply take the TSA officers doing the screening if they are using their AIT machines at all .
Update : The TSA Press Secretary Nicholas Kimball responded to my inquiry—”Was there any sort of TSA - broad policy to not use the machine today or is this an airport - by - airport decision?”—with this argument : “ No . Nothing to this at all . ”
