An unmanned aerial vehicle — better known as a drone — shut down evening aerial firefighting operations over the Lake Fire, which in turn burned more than 3 1/2 additional square miles overnight, authorities said Thursday.

The drone was spotted about 5:30 p.m. Wednesday flying between two fixed-wing aircraft battling the massive wildfire burning south of Big Bear Lake, according to Mike Eaton, forest aviation officer for the San Bernardino National Forest.
The sighting of the illegal aircraft prompted authorities to recall all aircraft battling the fire.
“We don’t want to deal with unknown aircraft in our airspace,” Eaton said. “They’ve got enough on their mind already … difficult terrain, difficult weather, winds and other things. They don’t need to be worrying about model airplanes or drones.”
Authorities could not figure out who was flying the drone or where it returned to. It was a fixed-wing type of plane, described as orange or red and about 4 feet wide.
