a tourist in windsor

Further to Simon's post below, my contribution is as follows...
For those of you who are unfamiliar with the location of Windsor in relation to London the number of low flying aircraft (on their way to Heathrow) as you are touring the grounds and seeing the ancient sites may come as a surprise.

Apparently one (allegedly) American tourist once voiced his surprise to a castle tour guide asking "why did they build the castle in the flight path of Heathrow?"

that is all
