Maybe that was also because there wasn’t a whole lot of halon in a discharge. If that problem could be overcome (large quantities, and maybe a halon-oxygen mix that would avert smothering problems for humans and beasts caught in it) then we’d have something that could be dumped on a large fire to put it out with little or no harm to humans and beasts.
You could be right - the nice thing is the forest wouldn’t be a concern about electronics damage from the residue LOL
