A U.S. Marine Corps MV-22 Osprey crashed into the sea off the eastern coast of Australia while trying to land Saturday. Three of the 26 Marines who were aboard are still missing, and reports say the search and rescue operations are progressing toward a recovery phase. The other 23 personnel have been rescued.

The Osprey belonged to Marine Medium Tiltrotor Squadron 265 of the 31st Marine Expeditionary Unit based in Okinawa, Japan, according to a press release. That release said the aircraft launched from USS Bonhomme Richard and was "conducting regularly scheduled operations when the aircraft entered the water," in Shoalwater Bay near Queensland. Media reports say it crashed trying to land on the USS Green Bay, hitting its flight deck.

According to a Marine press release, the Royal Australian Navy Clearance Diving team, which has been assisting in recovery operations, will resume such efforts Monday evening using a remote operation vehicle. The team, who had been aboard HMAS Melville, was able to locate the location of the crashed MV-22 Sunday.

Two of three missing Marines have been identified.

The cause of the crash is still under investigation and no further details have been provided. This story is developing.
