Nine soldiers were killed in a crash of two medical evacuation Black Hawk helicopters during a routine nighttime training mission over Kentucky, the U.S. Army said on Thursday, in one of the military's deadliest training accidents in recent years.
Crew members using night-vision goggles were flying two HH-60 Black Hawk helicopters, operated by the Army's 101st Airborne Division, when the aircraft crashed in a field late on Wednesday over Kentucky's Trigg County.
