Some people would argue that it would be a very sensible move for Thames radar function to move to Farnborough.
In a business sense:
No more band 5 for Thames (though LF deserve a higher banding than they are on, especially if the move happened)
In a practical sense:
Farnborough LARS covers most of Thames area anyways.
Farnborough are good at their job.
Don't know who Luton Radar could be farmed out to though...
