Both Los Angeles County and the L.A. City fire departments took the unusual step of flying night helicopter water drops over the weekend on the fast-spreading “Powerhouse” fire, which so far has consumed more than 32,000 acres. As of this morning, the fire, just north of Los Angeles, was classified as 60-percent contained. L.A. County dropped water on the fire from its two specially modified Sikorsky S-70 Firehawks, while L.A. City flew a Bell 412.
