Up close with the AT-802 with the help of Queen Bee: Loading retardant

As I understand it the valves used for loading retardant in the AT-802F -- 3 inch male kamlock couplers -- are standard in airtankers. The federal SEAT contracts require dual valves, so that retardant can be loaded from either side of the aircraft. When used in the "agricultural configuration, there is only one valve, on the left side of the aircraft.

Thanks to my friends at Queen Bee for the photos!
