Nine people were killed in a crash involving two Army Black Hawk helicopters in Kentucky, a military spokesperson said.
The deaths happened in southwestern Kentucky during a routine training mission.
A statement from Fort Campbell says the two HH-60 Black Hawk helicopters, part of the 101st Airborne Division, collided and crashed around 10 p.m. Wednesday in Trigg County, Kentucky. The 101st Airborne confirmed the crash about 30 miles northwest of Fort Campbell. The crash is under investigation.
The incident comes a month after two Tennessee National Guard pilots were killed when their Black Hawk helicopter crashed along an Alabama highway during a training exercise.
Black Hawk helicopters have long been a critical workhorse for the US Army in recent decades, providing security, transport, medical evacuations, search and rescue and other missions.
