Unless you a professional or public safety worker with official clearance do not violate public safety no fly. Not now. Not ever.
Yes, there are fine reasons to fly. We can even convince ourselves they are at least slightly noble reasons, but don't do it.
With care, the risk of taking down a rescue craft are small, but they are not zero. Your innocent even slightly noble flight could cause death. A low flying craft can come over the trees in seconds with your UAV in its path.
Your flight will also make life harder for both crew and dispatch. What will dispatch do when an unauthorized UAV is reported? Yep, they have no choice but to shut down and you keep people from getting the help they need. You help keep the fire out of control. You, no matter how wonderful a person you are in real life, are the irresponsible tool.
