Web site exposes Air Force One defenses:

Thus, the Air Force reacted with alarm last week after The Chronicle told the Secret Service that a government document containing specific information about the anti-missile defenses on Air Force One and detailed interior maps of the two planes — including the location of Secret Service agents within the planes — was posted on the Web site of an Air Force base.

The document also shows the location where a terrorist armed with a high-caliber sniper rifle could detonate the tanks that supply oxygen to Air Force One’s medical facility.

As of Friday, the document was still posted online. The Secret Service refused to comment on the document’s release.

The article doesn’t actually give the Web site where the documents are located. Of course.
