There's a sizeable cluster north of London on there - trying to work out why, I suspect it may be the proximity to Bedford Aerodrome and the fact that it's a very farming centered area and aerial photos can be very useful to farmers.

Historic England is the organisation name, so the title should probably be

Historic England Aerial Photo Explorer.
