Highly sensitive security information about the two Air Force One jetliners was removed from the Internet on Monday after it was reported that the data was posted on a public website, the San Francisco Chronicle reports.The security information is used by rescue workers in case of an emergency aboard Air Force planes, according to the Chronicle. Included in this particular \u201ctechnical order\u201d were details about the anti-missile systems on Air Force One and the location of Secret Service personnel on the plane, among other sensitive information that terrorists could use in an attack on the president\u2019s air carrier, the Chronicle reports.Air Force spokeswoman Lt. Col. Catherine Reardon told the Chronicle there was no justification for how the information became available for public viewing.\u201cIt should have been password-protected,\u201d she told the Chronicle. \u201cWe regret it happened. We removed it, and we will look more closely in the future.\u201dThe newspaper initially reported the existence of the technical order on Saturday, without divulging the sensitive details. It also alerted military and federal authorities immediately after discovering the information\u2019s existence, but the document remained online a week after that notification, according to the Chronicle.Reardon said the government and the military failed to remove the document sooner because they didn\u2019t appreciate the significance, the Chronicle reports. Officials \u201cmissed the bigger picture [and] failed to raise the document to a higher level,\u201d she told the Chronicle. \u201cThey saw that the document was not classified and thought they could not do anything about it.\u201dA Pentagon official, speaking on the condition of anonymity, told the Chronicle that putting the technical order online in the first place was deemed \u201ca cost-effective method for making the information available.\u201d\u201cBut it compromised information not only about Air Force One. ... It had information about our entire fleet,\u201d the official told the Chronicle.For related content, read Airport Security\u2019s Achilles\u2019 Heel and Suspicious Minds.Keep checking in at our CSO Security Feed page for updated news coverage.
