Nice work - I have noticed that you have added RAF Newton - this no longer exists as an airport, it is now partially an industrial estate and the site is mooted to become an "Ecotown" (new town). IIRC the former control tower is now an office block.

Presumably this needs to be deleted, but are there any tags for "location of former airport"?

Whoops, clicked okay before I finished!.

Also, RAF Newton has the been given the same icao reference as "East Midlands Airport - Nottingham, Leicester, Derby" (namely EGNX).

Also, with regards to "Nottingham Airport", Many local road signs (and all installed in the last five years or so) refer to the airport as "Nottingham (Tollerton) Airport", to avoid confusion with the much bigger airport at Castle Donington - these signs started appearing so after they renamed that one "Nottingham East Midlands Airport".

Presumably you have renamed it "Nottingham Airport" as this is what it's correct name is (and what it is know as aeronautically) - how should these two conflicting names be tagged? (The "Nottingham (Tollerton) Airport" compromise looks okay to me).

http://en.wikipedia.org/wiki/RAF_Newton suggests the proper code for RAF Newton is EGXN. Looks like a simple typo.
