The launch code for all U.S. Minuteman nuclear missiles for 20 years used the same code: 00000000.
Steven M. Bellovin, a computer science professor at Columbia, uncovered a startling fact. The launch code for all U.S. Minuteman nuclear missiles for 20 years used the same code: 00000000. Bellovin discovered this after finding a 2004 paper by Dr. Bruce G. Blair, a former Air Force officer who manned Minuteman silos.
