Missile alert crew asleep on duty at Minot AFB

The three man crew in a missile alert room at Minot AFB in North Dakota USA were found to be asleep on duty on the 12th of July even though they had the keys and launch codes to launch nuclear missiles, Minuteman III ICBMs, in their care. Minot AFB has already been in the news for the wrong reasons lately, it was here a B-52 was mistakenly loaded with nuclear tipped missiles and flew across America. The three men of the 91st Missile Wing's unauthorised nap is an embarrassment though USAF officials say there was danger to the security of the nuclear weapons in their care, the codes had been changed and were redundant apparently (so where were the correct codes and how would they be gotten to the crew in an emergency?) and the room was locked.
