A Canadian “Super Scooper” aircraft fighting the Palisades Fire in Los Angeles had to be grounded after it hit a drone flying in restricted airspace over the devastating blaze on Thursday, the local fire department said.

The plane landed safely but is out of service because the collision damaged its wing, a Cal Fire spokesman said.

A spokesperson with the California state firefighting agency, Cal Fire, says the aircraft landed without incident. The agency is urging people not to fly their drones over the fires.
