Ryan Coulter took these photos of two of the DC-10 air tankers making drops on the Washington Fire, June 22, 2015, near Markleeville, California. The photo above is Tanker 911, and Tanker 912 is below. The DC-10s carry 11,600 gallons of retardant, compared to the 2,000 to 4,000 gallons other large air tankers can hold.

Thanks Ryan!
