What about that very shady place between Aberdeen and Dundee - roughly inland from Montrose if memory serves - was/is it called RAF Edsel?
Stories of bat winged night arrivals rife there in the early '80s well before bat winged things admitted to.
Runway is huge, I've seen it from the air, but like the elephant's cage at RAF Chicksands appears on no map that I've ever seen.
Anyone know about this?
