LB - I understand RAF Station Honington is also the RAF Regiment Depot now?
(A role previously fulfilled by RAF Catterick - now Marne Barracks as part of Catterick Garrison)
I believe Valley was briefly RAF Rhosneigr, the eponymous railway station being closer to the aerodrome. If I recall correctly, anyone alighting there would have risked waiting for the tide to go out on their journey between the two types of station.
It was simpler idea being on one of 'HM ship's books' be it a steel, wooden, glassfibre or concrete one.
