Last week, two Air Force officers with the authority to launch nuclear missiles were stripped of their security clearances while being investigated for involvement in illegal drugs. The officers are based at Montana's Malmstrom Air Force Base, reports The Associated Press.
There were a number of lapses in silo security in 2013. In October, the AP reported that missile doors were left open while an Air Force nuclear officer was asleep. The Air Force requires that the blast door is shut when one crew member is sleeping during a 24-hour shift.
The previous May, a maintenance crew was allowed into an underground control center at Malmstrom Air Force Base, also a violation of Air Force rules. And In August 2013, failed safety and security checks led to the decertification of 17 military members, who were later retrained and sent back to work.
