A sailor who was injured when a helicopter made a hard landing last week in Virginia died Monday afternoon, the Navy said in a news release Tuesday.

The sailor, who was not identified by the Navy pending next-of-kin notification, was assigned to an East Coast-based Naval Special Warfare unit, the service said.

The sailor was taken to a local hospital after being injured during joint training at Joint Expeditionary Base Little Creek-Fort Story on Virginia Beach, the Navy said.

The Navy did not announce the type of helicopter involved. Past training at the joint base has included MH-60S Seahawks.

“The cause of the incident and tragic loss of a teammate remains under investigation,” the release said.

WTKR-TV in Virginia reported Thursday that three people aboard the helicopter had been hospitalized following a “hard landing.”

Maj. Jeff Slinker, a spokesman for U.S. Army Special Operations Aviation Command, said in an email that one of the aircrew members had been released from the hospital, while the second is in stable condition and is expected to be released soon.
