The Russian military says a navy helicopter has crashed during a night training flight, killing both pilots.
The Russian Navy said the crash occurred while the Ka-29 of the Baltic Fleet was performing a training mission late on April 12.
The Investigative Committee said on April 13 that the helicopter had been making a run to land on a ship. It said rescuers had found the helicopter's debris and the probe was ongoing.
The Ka-29 is a Soviet-designed twin-engine helicopter intended for use from navy ships.
