Investigation underway after two US Army Apache helicopters crash in central Alaska, killing soldiers.

Two Army AH-64 Apache helicopters from Fort Wainwright crashed near Healy, Alaska, while returning from a training flight. Each helicopter had two people on board, and the incident is under investigation. This is the second helicopter crash in the state this year, following the deaths of nine people in a Black Hawk helicopter crash during a training exercise in Kentucky last month.
