The launch code for U.S. nukes was 00000000… for 20 years
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.
The codes — known as Permissive Action Links (PALs) came to being following the 1963-1964 Cyprus crisis. The PALs were meant to give only the President of the United States the power to use such weapons. Apparently, this security feature was largely symbolic. For two decades, multiple presidents carried around a briefcase with the allegedly constantly changing codes, though it may as well have been filled with shredded newspaper. (Except for Reagan. He probably really did need the help to remember even this simple code.)
The code itself wasn’t very secret, either. According to Karl Smallwood, Dr. Blair explained:
“Our launch checklist in fact instructed us, the firing crew, to double-check the locking panel in our underground launch bunker to ensure that no digits other than zero had been inadvertently dialed into the panel.”
All of this basically nullifies the plot to every military thriller film from the ’80s.
But it’s not like our government would ever accidentally nuke us, right? Oh, they almost did that once already? Never mind. I’m going to go hide in a bunker and eat canned beans for the rest of my days.
