In an article about the Fort Hood incident there was this quote:
"She said officials at the base told people to shut off their heating and cooling systems so no one could crawl through the vents."
That's just crazy talk there.

When I worked at the US Army Corps of Engineers office in college, there was a change in security procedures that meant they had to go through and "man proof" all the duct-work in the building. Not exactly sure what that meant....I think the installed steel bars or something.
But surely it doesn't matter if the air is actually on. I guess people under stress say the strangest things.

There are probably some words left out of that quote that should be assumed to be there. Perhaps we should call John or Jeff to analyze and supply them?

Not that it requires an expert to figure this one out, but since I do a lot of HVAC design work in my job I might as well chime in. The only way to keep people from crawling through your ducts is to install steel security bars within them at the point where they cross the perimeter of any room you want to keep people out of. Shutting off the system entirely wouldn't do anything but what Bill said; make it quieter so it's easier to detect someone inside the ductwork.
