Chernobyl
The horror of human error is one wrought with extreme terror and how microscopic we are when faced with disasters. All of what we do is limited when what we do is captivated by the bottom dollar cost, we will sacrifice the lives of others if it helps balance a checkbook. Lives were lost and people suffered a great deal for the cheapness of the Soviet Union. What those people lost we will truly never know the depths of suffering. The world really saw the power of radiation and human error on April 26th, 1986.
