Ok, that didn’t take long.
NBC News:

CNET:

Fortune:

And this one from Fox News is exactly what I was thinking:

A lot more results. Many agencies are working on this, with some of them putting real fire-fighting drones in the air within the year (drones for surveillance of fires are already in use).

Problem with this, of course, is that it will be some time before this tech is widely available.

The lack of drones isn't the problem - it can crash the same as a pilot controlled plane.
The air currents close to and above the fire are the problem.

Keeping an aircraft airborne - someone has to make a decisions regarding safety and effectiveness of deploying water bombers ( as well as ground crew ).
The water bomber has to be able to get low so that the drop of water does not dissipate before reaching the target. For an aggressive fire, that is difficult to do.
The fire in question was so aggressive that it was unsafe for people as well as machinery to be close to the fire front either on the ground or in the air.
The decision to ground the aircraft was done for safety reasons, as well as that the water drops from a height that would be flyable would imprint on dousing of the fire. - the water would evaporate before hitting the ground.
See post 19 for a review of the fire in question.
We are not talking 100's of feet, but thousands, even tens of thousands for safe flying. for an aggressive fire.
