Baku, April 28, AZERTAC

Two U.S. army helicopters collided and crashed Thursday in Alaska while returning from a training flight, killing three soldiers and injuring a fourth, according to AP.

Two of the soldiers died at the scene of the crash near Healy, Alaska, and a third died on the way to a hospital in Fairbanks, the Army said in a statement. It said a fourth soldier was being treated at a hospital for injuries.

The names of those killed were being withheld until relatives could be notified, the Army said.

Each AH-64 Apache helicopter was carrying two people at the time of the crash, John Pennell, a spokesperson for the U.S. Army Alaska, said earlier Thursday.

The helicopters were from the 1st Attack Battalion, 25th Aviation Regiment at Fort Wainwright, based near Fairbanks.

“This is an incredible loss for these soldiers’ families, their fellow soldiers, and for the division,” Maj. Gen. Brian Eifler, commanding general of the 11th Airborne Division, said in the Army statement. “Our hearts and prayers go out to their families, friends and loved ones, and we are making the full resources of the Army available to support them.”

The Army said the cause of the crash was under investigation and more details would be released when they become available.

The crash is the second accident involving military helicopters in Alaska this year.
