Technically due to the short sector length the runway physical sizes at both aerodromes may be adequate. However, to operate for public transport purposes the aerodromes would need to be licensed, Sandown recently gave up their licence plus there is doubt as to the continued use of the site as an aerodrome.
Bembridge remains licensed but woud need massive investment to improve the aerodrome's infrastructure to support scheduled air transport movements. This would probably require provision of an ATC Unit and instrument approaches to ensure some level of regularity of service. Who is going to pay? Sounds far fetched enough for the EU to pour in millions to achieve it!
Finally who is going to operate the service? Would suggest that any chance of sucess woulod need something the size of an Islander, very appropriate as Bembridge is the birth place of it. Problem then is to how is the aircraft going to make money for the rest of the day after a few SOU roundtrips?
Nice thought, but cannot see it happening.
