When I was in junior high, we had air raid drills every so often. This was during the cold war after nuclear bombs had been dropped during WWII. Because there was fear that the Communists would drop bombs on America, the schools had air raid drills, I guess to offer some protection for school children.
When the siren went off during school hours, we went out in the hall and knelt on the floor and faced the lockers. On television I've seen what the nuclear bombs do to buildings and land. I can't think kneeling on the floor in the hallway really offered any protection. I'm not really sure what the purpose was.
We all believed firmly that a bomb could come at any time. Some people built underground bomb shelters to go to in case of emergency. It now sounds as though the whole idea of being bombed should have been very terrifying, but I don't remember being very afraid. I would be now, though.
Sometime after that we didn't have drills anymore, and there weren't any drills when I was in high school.
Is it better to practice for something that you can't be saved from or is it better to acknowledge the impossibility of being protected? Maybe that's why the drills didn't go on after my junior high years. Maybe we just got complacent.
