Preliminary results released after 3 Idaho National Guard members killed in helicopter crash BOISE, Idaho (KIFI) — The Idaho National Guard announced Friday the preliminary results of the U.S. Army Combat Readiness Center’s investigation into the Feb. 2 UH-60 Black Hawk mishap that resulted in the death of three Idaho Army National Guard aviators. The Safety Investigation Board, from Fort Rucker, Alabama, found although weather played a significant role, the primary cause of the accident was the crew’s inability to successfully complete an emergency procedure before impacting the ground. The crew, consisting of Chief Warrant Officer 4 Jesse Anderson, Chief Warrant Officer 3 George “Geoff” Laubhan and Chief Warrant Officer 3 Matthew Peltzer, was conducting a routine training flight Feb. 2 south of Lucky Peak near Boise. As the crew was returning to Gowen Field, the weather degraded rapidly, and they inadvertently lost visual references to the ground and surrounding terrain.
