Officials say three U.S. military personnel have been taken to a hospital, one with critical injures, after a U.S. aircraft crashed on a north Australian island during a multination military exercise. Rescue helicopter operator CareFlight says one of the injured was in a critical condition and other two were in stable conditions. Australian Prime Minister Anthony Albanese said all three injured are American. The Australian Defense Department said the Bell Boeing V-22 Osprey tiltrotor aircraft crashed on Melville Island during Exercise Predators Run, which involves the militaries of the United States, Australia, Indonesia, the Philippines and East Timor. The injured were flown by helicopter to Royal Darwin Hospital, about 60 miles to the south.
