Just over half (92) of the 183 nuclear missile launch officers at Malmstrom Air Force Base in Montana have been implicated in a widening exam cheating scandal, the Air Force said on Thursday, acknowledging it had "systemic" problem within its ranks.

The cheating was discovered during an investigation into illegal drug possession among airmen, when test answers were found in a text message on one missile launch officer’s cell phone. The Air Force initially said 34 officers either knew about the cheating or cheated themselves.
