Here's the latest from the Times:
As a hot wind shifted north and drove the flames toward Onyx Peak east of Big Bear Lake, fire crews deployed to save homes scattered among brittle-dry pines — waiting for help from a DC-10 laden with 10,800 gallons of retardant.
It never came. Shortly before 5 p.m. on Wednesday, an incident commander on the ground spotted a hobby drone buzzing near the drop site at 11,000 feet. The drone was also seen by the pilot of one of the tankers. The air tanker had to turn back, as did two smaller planes following it. All helicopters were grounded as well.
“These folks who are handling these drones, I have to assume they have no idea what they're doing,” Chon Bribiescas, a spokesman for the U.S. Forest Service, said Thursday. “They not only endangered the folks on the ground, but they endanger the pilots.”
Officials fighting the Lake fire in the San Bernardino Mountains scrambled to warn the public that it is illegal and dangerous to fly drones in restricted airspace around a fire. Unmanned aircraft are particularly hazardous because authorities have no idea who is controlling them or how they might maneuver.
The DC-10 had to divert and drop its retardant on a fire along the Nevada border, while the two smaller planes had to jettison theirs because they couldn't land with that much weight. Officials said the failed mission cost between $10,000 and $15,000.
As the planes returned to their base by Lake Arrowhead, pilots spotted another drone 1,200 feet above ground in the restricted fire zone, far above the 400-foot limit set by the FAA for unmanned aircraft.
“It's infuriating,” Bribiescas said. It was spotted flying between two fixed-wing aircraft battling the fire.
Authorities could not locate the operators of the drones. They described the aircraft that obstructed the retardant drops as an orange or red fixed-wing drone with a wingspan of 4 feet.
Mike Eaton, forest aviation officer with the U.S. Forest Service, said police would be patrolling mountain roads, looking for people flying drones in the temporarily restricted airspace set by the FAA.
Speaking at a news conference at the San Bernardino Airtanker Base, Eaton urged people to stay away from the fire. Red fliers were stapled around a fire map that read: “If You Fly, We Can't.”
Eaton said air drops had to be shut down three hours early on Wednesday because of the drone.
“The fire certainly grew because we weren't able to drop the retardant,” said. “We had to shut down subsequent missions that could have possibly contained the fire.”
By Thursday morning, the fire had grown to 23,199 acres and was 21% contained.Twenty-four hours earlier, 38% of the fire was contained. That was before the Drone incident, however. Later in the afternoon it had spread a mile north to Heartbreak Ridge.
As unmanned aerial system technology has become more prevalent, so have run-ins between civilians using it and government agencies that consider it a danger. The U.S. Forest Service issued a statement last year on civilian drone use, warning that it could interfere with firefighting efforts.
In July 2014, CalFire crews had law enforcement confront a drone operator near Plymouth in Northern California after he flew the aircraft near a 3,800-acre blaze as crews made water drops.
