Nine US Army personnel were killed on March 29, when two HH-60M Black Hawk medical evacuation (MEDEVAC) helicopters collided in darkness at 2200hrs (local time) near Fort Campbell, Kentucky. Five personnel were on board one helicopter and four on the other. There were no survivors and both helicopters were destroyed. The weather was calm and clear at the time.
Both helicopters were assigned to Company C/6th-101st Aviation (Air Assault) at Sabre AHP, Kentucky, as part of the 101st Combat Aviation Brigade. They had taken off from Campbell Army Airfield, Kentucky and were undertaking a routine training exercise with night-vision goggles (NVGs) at the time when they collided near Maple Grove Road and Lancaster Road and crashed near Highway 68, close to Cadiz in Trigg County. They came down in an open field near a residential area but there were no injuries on the ground. Eyewitness reports say the utility helicopters were flying low and close together just before there was an explosion and both disappeared from view as their lights went out.
