Keep It Simple - Lessons From The Cold War

In the early 1980s, a Russian pilot defected with his aircraft. When the US military examined the aircraft, they found the nose dropped and behind it were an assortment of vacuum tubes. At first this confused the American experts, until they tested the idea that vacuum tubes do not burn out when exposed to an Electromagnetic Pulse. It was another KISS (Keep It Simple, Stupid) principle idea that worked just like using a pencil instead of trying to design a pen that works in zero gravity.
