NIFC Air Tankers
KTVB.com out of Boise, Idaho, has an interesting article on the air tanker operations at NIFC headquarters:
On the tarmac each plane's special firefighting system is loaded with retardant for fire lines.The fire retardant comes in powder form and contains fertilizer salts and a coloring agent. It’s mixed with water inside a big tank and loaded onto planes to drop on fires.
“We stretch the loading hose out to the air tanker. It takes about six minutes to load 2,700 gallons of retardant onto the airplane,” said Grantham.
