Northolt closure
The intention of getting out of Lippitts Hill continues.
After the plan to move to Elstree was shot down by a successful NIMBY campaign new places were sought and Northolt was again deemed the favourite.
The news that someone [anyone] wants to actually close Northolt must be a bolt from the blue in that planning scenario. Even though it may not happen soon it was at one time unthinkable. The fact that someone is now thinking it out loud must be a blow.
There are other options, including North Weald, but that has potential NIMBY problems with new house building so they would need to get in quick to be established before the new, non aviation minded, occupants of the new houses affect them.
The police generally are poor at long term planning but if they do not get it together soon they will either be stuck with Lippitts Hill forever or have no home close to London at all.
