They need to use this to fight fires-Supertanker

For whatever reason the FAA won't give them them the approval although it would be a great asset in fire fighting.

The Evergreen Supertanker is equipped with a pressurized liquid drop system, which can disperse retardant under high pressure or drop retardant at the speed of falling rain. This system allows the aircraft to operate within its design criteria.[2] Using the pressurized system, the aircraft can deliver retardant to the scene of a fire while flying at a height of 400 to 800 feet (120–240 m), at approximately 140 kn (260 km/h, 160 mph), configured as if it were on approach for landing.

The Evergreen Supertanker’s tank system can be configured for segmented drops, allowing the contents of the tank to be released at multiple intervals while in flight.[2] According to the company, the aircraft is capable of laying down a swath of fire retardant three miles (5 km) long and as wide as an American football field.[9]

Because the tanker is based on an airliner, it can fly at speeds of around 600 mph (970 km/h; 520 kn) during cruise.
