Windriver -I too was a 645 'graduate' but started my training at Dishforth, which meant a drive up to Leeming after flying each night, for o/nt accommodation. Not the most pleasant of journeys in a packed, geriatric landrover. Leeming was also home to 11 AEF (I think) at that time.
We all relocated to Catterick about half way through my course, which took us from enjoying the luxury of a super sized field to something more akin to a postage stamp. And I do also remember a number of pretty quick circuits being a feature of Catterick life, but there was no shortage of flying time.
Fond memories, like so many of those who have responded to this thread
