Two crew members are dead after their Army National Guard helicopter crashed Thursday night in Boise, a spokesman for the Idaho National Guard said. Col. Tim Marsano said the two pilots were on a local night-time training mission when the Apache combat helicopter crashed about two miles south of the Guard base at Gowen Field near Boise's international airport. Marsano did not release any details on the guardsmen, both of whom were male, but said the incident is being investigated and autopsies would be done.
