It would be easier for a "terrorist" to follow your plan Scythe and buy a remote control helicopter or plane from Maplins. learn to fly it without having to register for pilot lessons & use it as a drone to fake an attack on the Olympic environment. ie, if they can get the military to start lobbing missiles around at unmanned highly mobile targets over a heavily populated area or venue and without putting themselves in the firing line, then I think a terrorist would be a bit cleverer than our political planners. Using drone tactics back at its originators would be a frightening prospect in our crowded cities. I think the military planners should do some lateral thinking on this one.
