(NBC NEWS) The careers of four Air Force officers who held the keys and codes to launching nuclear missiles are likely over after they were severely reprimanded for leaving blast doors open on their underground launch capsules, Air Force officials told NBC News on Tuesday.
The two incidents occurred earlier this year at Minot Air Force Base in North Dakota and Malmstrom Air Force Base near Great Falls, Mont., the officials said. The officers involved weren't identified in the incidents, which were first reported Tuesday by The Associated Press. Security wasn't breached in the incidents, The AP reported.
