I've flown into Westbury-sub-Mendip in an Auster Autocrat, that gentle curve makes for some fast and precise footwork.
Visited the site to check it out but still overflew 3 times before committing as it looked a damn sight shorter and narrower from 500ft!
Also had/has sizeable industrial unit at the Southern end not far from the threshold, I'm guessing the TB9 would have needed a very favourable wind.
