I was a brat there in '61 when the Berlin Wall went up. For a few hours/days we really thought we were going to war. Truck sirens around the patch at 3am to get everyone up, Regiment running around digging fox holes in people's flower beds, my father (airframe/engines) strapping a pistol on in the bedroom..... Never did that even in WWII.
Scary stuff. What distance did they say it was from Gut to the inner-German border? 60 miles? 4.5 mins flying time for MiGs?
