On Thursday, Jan. 9, a Super Scooper firefighting plane was grounded after it collided with a drone illegally flying over the Palisades fire area. The aircraft, which can drop 1,600 gallons of water at a time and replenish its supply in five minutes, will likely be out of use for the remainder of the Palisades fire.

Firefighters were slowly making progress in their battle to contain the inferno that has razed swathes of Los Angeles' Pacific Palisades neighborhood to the ground, but still-spreading flames threatened communities in the populous San Fernando Valley on Sunday.
