Not to mention Air Support not being able to fly.
There's no Reservoirs any where close to providing enough water for the fiasco that unfolded.
I'm fortunate to have Lake Isabella as a source for helicopters and bordering Sequoia National Forest brings all Aerial support being retardant or water to help keep the further spread of destruction to forests or developed/structures.
Regardless it is obviously never an outcome that is preventable to an extent.
