5 times we almost nuked ourselves by accident

5 times we almost nuked ourselves by accident: "This is how NORAD learned not to run computer simulations of Soviet nuclear attacks on the systems used to respond to actual Soviet nuclear attacks.

The president's shielded emergency plane was put into the air too (although they couldn't get the president on it in time)."
