This is a fun one. From what I can gather in 2013 reports came out regarding Officers falling asleep with the Blast Doors open while on duty in a silo housing nuclear weapons. These are huge doors intended to keep bad guys from getting inside. Now in some reports I also saw a reference to pizza delivery guy being involved in finding the doors open. As if that was not funny enough it now looks like what happened was that they leave the blast doors open when they order pizza per their agreement with the pizza delivery company who had a rule that if the pizza was later than 30 minute it was free. So it sounds more like they left the door open for the pizza guy and fell asleep.
Oops I left the missile unlocked! (5/10)
