Otherwise, if one had terrorist tendancies, wouldn't it be easier to enter said tower block with a team, go to the roof and shoot the squaddies who're probably dozing in the sun, then nick their missiles and shoot down an airliner yourself?!
A great idea but I wonder if the 64 virgins would be a bit of a give-away? I mean, you cannot find a virgin over 13 in the UK these days....
Those missile sites must be heavily guarded, or as you say dummies, because it would be pretty easy to do what you suggest.
