Apparently a ??Dutch?? royal was watching from ground level right next to the station.
Also a link here with a pic of a crumpled 109 that fell onto a London street (see page 4):

I think many of the civilians rushed to shelters and the tube network when the air raid sirens started, so casualties from aircraft crashes were minimal, apart from the poor pilots who couldn't bail out in time of course.
