One of the guys @ our company was a military flight controller. He has mentioned that any time any type of nuclear material was relocated, there was a "silent hoopla" of amazing proportions. (All lights off, camoed Marines laying in fields, unmarked trucks 1/2 filled with equipment[other 1/2 filled w/ 50cal nest], decoy trucks, 15-20 marines in the blacked out tower, etc.)
Just a thought.
