PN, during my time we constructed an Alternate Local, using a redundant dispersal caravan semi-buried in the grass. Naturally, that meant the controller's eye-line was only a few feet agl. After a lot of walking about I found a spot where, even from that low altitude, you could see both ends of the rw.
Looking at Google Earth, it seems to have been developed. It's at the end of the stub road running NE from F Dispersal, with a proper bund around it. There's an unclear image of something semi-buried you zoom to ground level view in GE. Can anyone validate that?
(Curiously, there's a lot of detail in Ground Level view, which I wasn't expecting to find at an MOB)
