Saving London 2012 from air attack

If terrorists are planning to attack the London Olympics, then the joke is on us, because the remedy will probably be worse than the "cure". The idea is that, in the event on a possible air attack, ground-to-air missiles will be launched from strategic points around the capital. Including from the tops of residential tower blocks in London's east end - the part of the capital where the Games are to be held. Remember the London Marathon the other week, which begins near me on Blackheath? This is the heath looking roughly north-north-east:

This is the same view with missile launcher, taken on Wednesday or Thursday.

Missiles primed and ready to go?

And if they shoot down something that might have been threatening the Games? Where will the pieces fall, exactly?

Well, presumably somewhere else in the capital.

Just as long as it isn't the Games...
