No, it's my faulty memory that's all. Looking at Google Earth, there are ground marks on the other side of the taxiway to the NE of the remaining VOR - was that where they were? I'm sure I can also recall "Sally B" and Don Bullock's Invader parked near them somewhere up at that end during 1978 or 1979.
Finished "The Road to Biggin Hill" now, interesting book and a great character!
