Whenever Russia near US airspace, Sarah Palin's phone does not ring, despite her claims.

NORAD has slammed GOP VP Candidate Sarah Palin's claim to CBS' Katie Couric that she has command authority over US space guardians.

Spokesman for the North American Aerospace Defense Command, Air Force Maj. Allen Herritage told the NY Daily News. "She doesn't have any role in that process."

"The authority to launch and respond to a Russian incursion lies with the Alaska NORAD Region commander" solely.

Moscow's bombers have skirted Alaskan airspace 20 times but have not violated it during Palin's tenure.  

And when interceptors scramble from Elmendorf Air Force Base in Anchorage, Sarah Palin is not speed-dialed.

"The commander does not call the governor," Major Herritage clarified.
