While out for a walk recently I spotted this Bloodhound AA missile in a (large) garden. As it was behind a high wall one can only speculate about what else might lurk therein.
Interestingly, when I showed this to some of the chaps at the Sheffield Club they were rather less concerned with "why have an air defence system in your garden" and the conversation moved quickly on to what the most suitable system would be! Leading the field so far is a Bren on an AA tripod. Worrying really, isn't it?
