NOT necessarily something the United States Air Force wants you to know about!
From The UFO Chronicles:
"Malfunctioning Nuclear Missile and Fear of Accidental Launch (1984)"
As was reported three years after the fact by the main stream media as it existed at the time. Click on image to see a larger view.
"Air Force officials parked an armored vehicle on top of a Minuteman 3 silo in 1984 to prevent what appeared to be the launch of a malfunctioning nuclear missile .... The guidance system on a Minuteman 3 missile loaded with 3 warheads malfunctioned Jan. 10, 1984."
NO DANGER of a real launch of an intercontinental-ballistic-missile [ICBM] carrying three atomic warheads.
BUT IT WAS THOUGHT SUCH A POSSIBILITY DID EXIST AND REMEDIAL MEASURES OF AN EXTREME NATURE HAD TO BE DONE!!
Only in a very vague manner was I aware of this incident. That process of preventing an accidental launch of an ICBM thought through with some thoroughness it seems.
AND THE SOVIET RESPONSE AT THE TIME TO THE MISSILE LAUNCH AND ATOMIC DETONATIONS ACCIDENTAL WOULD HAVE BEEN?
