I was in US Air Force Survival school at Stead AFB, Nevada.
They locked the base down, increased the “DEFCON” and then cancelled all parties or celebrations post graduation...it was cold enough for three of us to get frostbite. Spent 7 days on snowshoes, escaping and evading. 18 inches of snow one night just about buried us in our 2 man “tent,” made with a parachute canopy. Those were the days!
“...then cancelled all parties or celebrations post graduation...”
9/11 was like it, but because of internet, cable, you could escape it for a while. The whole country was more or less held captive by the JFK thing for the four days from assassination to funeral. It was really like a weight being lifted when it was all over.
Sounds like NOT fun!
