MIAIMI (AP) — The largest sections of a Black Hawk helicopter that crashed during a nighttime training mission have been pulled from the waters off Florida's Panhandle as salvage operations continue to recover the remains of all seven Marines and four soldiers who were killed.

Eglin Air Force Base spokesman Andy Bourland says recovery operations were expected to finish late Saturday.

The debris pulled from the Santa Rosa Sound will be moved to the Air Force's Hurlburt Field to be examined by investigators.

Bourland says recovery operations will continue "as needed to ensure we collect as many human remains as possible."

The commander of Marine Corps special operations forces has said those aboard the aircraft had tried to abort their mission early Tuesday when they decided it was too risky.
