Ironic the way it lists Finningley Doncaster-Sheffield Robin Hood as an 'unlicensed farm strip' ..
Not sure which waypoint you're looking at; if you could tell me the ID number that shows in the URL it will help pin it down.
"FINNINGLEY" may be listed as "Airfield (unlicensed, farm strip or private)" because I guess it was once and one of the lists of airfields we used had all kinds of historic ones.
Meanwhile "Doncaster Sheffield Robin Hood" is listed as a licensed airfield with its approach plates and all that other stuff.
