I've flown into Lee in the past and would do again if it were open to visitors.
For someone needing a hard runway the nearest choices to Portsmouth are Southampton, which is short of space and will not permit aircraft to be based there, Shoreham, or Farnborough.
Lee's got a lot going for it. It has the hovercraft museum on site and with the right access you could exit the airfield, cross the road and be on the beach.
It's also got excellent potential for aviation related businesses. Those that are already on site have been given 30 days notice that they will no longer be able to use the airfield because the aerodrome manager has failed to properly manage the airfield. In particular he has failed for over a year to sign the letter of agreement with DARA Fleetlands, whose ATZ encroaches on the aerodrome boundary and he has not applied for a dedicated radio frequency for Lee.
It is a farcical situation that the person charged with running the airfield is now using his own failures as a reason to deny the use of the facility to others.
That said, the airfield is owned by The Maritime and Coastguard Agency and the responsibility is ultimately theirs.
