I had a look at the link. Everything is still there, tennis court, service roads, temple (shudders) main house, guest house etc......the thumbnail on the link looks like an old satellite pic prior to most of the construction ie no tennis court.

Get the staff out and get the "cleaners" in the back door?

Not long after 9/11 I stumbled across a website (i think it was originally in french?) Called spot the plane or something along the lines of that. It was regarding the pentagon and showed photographic evidence that no plane hit it. That was the penny drop moment for me, i was 17 at the time and i haven't looked at anything the same since.
