I need to to clarify on our last post as it wasn't totally accurate.
What we saw fly by the window was not President Bush but his arrival convoy that includes a back-up 747, a 757 jet and four helicopters, the presidential limos, his security force and other things that go with him when he travels. I'm not sure why all the fighter jets were in the convoy though...
Anyway, he didn't actually arrive until mid afternoon yesterday where he was quickly off to Windsor castle for tea with the Queen.
Yesterday we kept an eye out for Air Force One but it flew directly over the flat so I could only briefly see the bottom of the plane.
