Engineers should make sure that everything they design and build does not have deadly defects. For example, a fuel system control processor with a deadly defect was on Flight 143 in 1983. The plane ran out of fuel before reaching its destination. Thankfully, the plane landed without killing anyone. Humans need help to accurately measure how much fuel is in the tanks, and that help must be trusted to give an accurate measurement so enough fuel is in the tanks for the plane to reach its destination. There are stories of a deadly defect in dialysis machines. Instead of moving the blood of the user through the machine and cleaning it, the machine would start cleaning itself and kill the user as it pumps solvent through the user's body. It is imperative that engineers eliminate deadly defects.
