Walking, or rather marching smartly (as B@stard Bill was probably watching), to the F-4 OCU early one morning, I was surprised to see a C-130 make a low approach and go around somewhat adjacent to the ATC tower. This process continued a couple of times until it finally landed.
It seems that 'someone' in Ops had overlooked the early movement and the tower wasn't manned in time. Very sensibly the Albert drivers decided not to land, but advertised their frustration quite noticeably until someone in the Flying Prevention Branch arrived to switch on the radios.....
No doubt BB invited SATCO and/or SLOPS for a no-tea, no-biscuits chat?
Then there was the 1974 Gnat incident, where a QFI landed without clearance. Or rather he did have clearance to land at Shawbury, but
actually landed at Sleap, causing much consternation in the process!
