Pentagon to Test Invisible Gases in Crystal City
March 2nd, 2008Via: Examiner:
The Pentagon is scheduled to release an odorless, invisible, and yes, harmless, gases into the city Thursday to test how quickly they spread through buildings, officials said.
The test is part of the military’s national security preparation for the capital area.
Over the past few years, the defense agency has worked with Arlington County to set up chemical sensors throughout the county, where thousands of defense employees work in leased office space.
The Pentagon has also supplied the sensors and accompanying monitoring equipment to Arlington for the county’s own use.
“Within minutes, if someone attacks the Pentagon, it becomes a problem for Arlington,” Pengtagon Force Protection Agency Director Paul Benda said.
The sensors scan broad areas, Benda said.
If weather cooperates, the Pentagon will release perfluorocarbon tracers, which are commonly used commercially to detect leaks, and sulfur hexafluoride, a common window insulator filling, near the Jefferson Plaza building at 10am on Thursday and Friday.
Officials in yellow vests will set up 80 battery-operated samplers – toolbox-looking cases with 12 air tubes inside of them – throughout Crystal City and will check the air samples in the tubes afterwards to evaluate how quickly and how high the gases spread.
The data will help the Pentagon and Arlington shape their lockdown policies for chemical and biological attacks or accidents, and will also help them determine the most effective locations for sensors.
“We want to place our sensors so we can detect this stuff as quickly as possible,” Benda said.
The test, dubbed “Urban Shield: Crystal City Urban Transport Study,” is similar to one conducted in Manhattan a few years ago, officials said.

Kevin,
If you don’t know, I think Comcast is blocking your “page” tonight. Three tries with same “page not available.” Got here through a google search for cryptogon.
This article may be why.
What a hoot.

Sure, and who’s going to confiscate all of the evidence – when things go wrong, just as they did on 9/11. You know all those cameras on 495 that would have recorded just what it was that flew into the Pentagon. If this odorless, “benign gas” (what’s this gas going to be – a big fart?) Turns out not to be so? Sheesh. Fill some potholes with the money you assholes.
Donald Rumsfeld and Poindexter must surely still be at work at the Pentagon. Remote access to Pentagon encrypted systems must still be allowable to these two numbnuts. How much more bizarre can it get – wait, please don’t tell me.
