Why Drones?
In most wildfire scenarios aviation stops when the sun goes down. Drones can provide a continuous stream of water dropping operations on the fire when manned aircraft no longer fly. This allows agencies to take advantage of the cooler temps and reduced fire activity that comes with night. The drones would fly until manned aircraft are available the following morning.
Drones are unmanned allowing them to fly in smokey dangerous conditions that would otherwise limit manned aircraft. They are cheaper to maintain and operate potentially saving agencies and states millions of dollars in suppression costs. Having drones fly on smaller or less active fires would allow larger manned aircraft to be available for more critical needs. Drones eliminate the need for pilots to fly in the dangerous dead mans curve by assisting with water dropping and cargo missions. Even allowing for more precise drops and placement of gear and equipment.
