In the early days of aviation there were many small airports round the UK. Gradually they competed to become major regional airports else they were deemed obsolete. A few like Meir extended their lives by serving adjacent aircraft factories during the war.
The majority of such sites are probably now housing estates. Stobart have diversified into trying to turn minor airfields into point-to-point regional airports eg Carlisle Lake District Airport - the opening of which has been delayed owing to problems recruiting/training adequate numbers of qualified staff.
