Don't Fly To London...

...during the olympics. If your pilot strays or the aircraft electonics go haywire, you might fly right into an anti-aircraft battery that has orders to blow you out of the sky.

The British government is surrounding the olympics with anti-aircraft missiles sites whose only purpose will be to shoot down any aircraft that wanders too close.

I wonder what they are doing about the possibility that terrorists(of any stripe) have already smuggled in a small tactical nuke or an old Russian suitcase nuke, and have already planted it somewhere, all set to do massive damage.

That's what I think the bad boys would do, rather than try to fly hi-jacked planes around again.
