Two helicopter pilots who crashed while they were fighting a wildfire in Utah are dead, officials confirmed Saturday. The pilots were killed when their Sikorsky Skycrane helicopter went down Friday morning, according to the Sevier County Sheriff. Officials did not identify the pilots but said they were employed by Helicopter Transport Services, which was contracted by the U.S. Forest Service. Numerous fires also were burning in other parts of the West, including one that closed part of Mount Rainier National Park in Washington. Meanwhile in Oregon, hot and dry conditions helped an uncontrolled fire spread beyond 30 square miles (77.7 square kilometers).
