Despite the fact that the airport at Manston in Kent is 124 km (77 miles) from London, it insisted on calling itself London Manston Airport as can be seen on this "2½ inch" OS map (1:25,000 on paper or 625 pixels/km in the full size version
) from 2005.
It now calls itself by the more realistic title of Kent International Airport
. Same map in 2008:
