No hope of survivors from downed Australian military helicopter

Authorities have lost hope of finding survivors after a military helicopter plunged into the sea during war games over the weekend, Australian Defence Minister Richard Marles said Monday. 

Rescuers initially clung to slim hopes they would find the four crew members alive, but those were dashed after the discovery of "significant wreckage" from the aircraft, Marles said.

The chopper had been taking part in the large-scale Talisman Sabre exercise, which brings together 30,000 military personnel from Australia, the United States and several other nations.
