Nice one..
Can't post this one but had an email Apparently showing the last Harrier Fly past the Houses of Parliment , Close up you could not really make out anything unusual but the further away the picture was it bacame quite clear what their message to Number 10.. was..

And I belive there is a restaurant also named Foxtrot Oscar in London as a clue..

It was Obviously photo shopped but pretty good..

Sure if you search hard enough you will find the picture on the WWW.
