RICHFIELD, Utah (AP) — A heavy-lift helicopter with two people on board battling a large Utah wildfire crashed as firefighters worked to corral an uncontained blaze in Oregon that killed a bulldozer operator, officials said Friday. There was no word on the conditions of the people aboard the helicopter as officials said they couldn’t immediately reach the crash site. It had burned almost 14 square miles (36 square kilometers) by Friday with no containment, according to the U.S. Forest Service. The downed helicopter was one of seven working a fire in central Utah that was caused by lightning on July 27. Conditions were good enough for aircraft to fly when the helicopter crashed, said Tyler Hecht with the Great Basin Incident Management Team.
