Wildfires continue to burn in Northern California, with nearly 8,000 firefighters trying to contain the blaze that has claimed at least 31 lives since Sunday.
Officials said that at least 820 firetrucks, 73 helicopters and 30 planes are being used against the fires that have scorched 191,000 acres in the state's wine country.
The California National Guard released footage Thursday giving an up-close look at how helicopters are used to fight the wildfires. The video, posted on Twitter, shows a water bucket drop over the blaze.
According to SEI Industries Ltd., a manufacturer of helicopter buckets, the lightweight device hangs from cables below the chopper. To fill up, the pilot lowers the bucket into a body of water. The bucket is then carried to the fire and the water is unleashed using a pilot-controlled valve.
The California National Guard said that the goal is not necessarily to extinguish the massive wildfires, but rather to contain the fire so it burns out.
As of Friday, the 43,000-acre Atlas fire was 7% contained, the 34,000-acre Tubbs fire was 10% under control, and the 32,000-acre Mendocino-Lake Complex fire was 10% contained.
