JUNCTION CITY, Calif.  Nine people were presumed dead and four were injured after a helicopter ferrying firefighters battling one of several wildfires in Northern California crashed and burned Tuesday night. It was one of the deadliest wildfire accidents in the nation’s history.
It is believed that all but one of the dead were firefighters, but the authorities were still working on Wednesday to confirm the identities of the victims, said a spokesman for Carson Helicopters, the company that owned and operated the helicopter, a Sikorsky S-61N.
It crashed about 7:30 p.m. Tuesday in a remote area of the Shasta-Trinity National Forest near here, about 35 miles northwest of Redding, said Ian Gregor, a spokesman for the Federal Aviation Administration.
The helicopter carried 11 firefighters and 2 pilots, said Bob Madden, a spokesman for Carson Helicopters.

Four out of the 13 members of the flight were rescued from the crash, though they received severe burns. Sharon Heywood, a United States Forest Service spokesperson said that the three firefighters and pilot had been initially airlifted to Mercy Medical Center in Redding. However, because of the critical condition of two of the firemen and the pilot, the three of them were transferred to UC Davis Medical Center in Sacramento. The remaining firefighter remains at Mercy Medical Center in serious condition.

The helicopter, which is owned by Carson Helicopters, crashed "under unknown circumstances," according to Ian Gregor, a spokesman for the Federal Aviation Administration (FAA). The helicopter crashed 35 miles northwest of Redding in the Trinity Alp region, at roughly 7:30 p.m. Tuesday evening, said Gregor. Both the FAA and National Transportation Safety Board investigators were on the scene of the crash.

The firefighters had been fighting flames covering more than 27 square miles in the Shasta-Trinity National Forest. They had been working near the north end of the fire, which is reportedly 87% contained.
