There was one old boy at one SE Mil base
Smidge up, Smidge down. Links a bit , Richts a bit.
All done on CAVOK days when it was requested for controller currency.
Then there was the cavok days when they were training a newbie and the ex lightning jock in the LHS would go Right when they had requested left etc and when challanged said he was inverted.
Next day Mr links Richts asked us to comfirm the blue bit was up and the brown bit was down.
It really is a cracking service for pilots and I hope that we do retain at least some coverage in the UK.
