Holy shit. Somebody just made a casual remark in a comment that the Princess Diana memorial in Kensington Gardens also resembles the letter "Q" from the air. So I took a look. Here's what 30 seconds of searching turned up.
Turns out the Royal Prussian Family of Windsor that is as British as I am strongly objected to this memorial for Diana. Did the resistance have something to do with the SHAPE of the memorial seen from the air?
