The sad/realistic issue is cost. What does it cost to operate 944? Is that something that is negotiated every year/season with state fire authorities? I don't know enough about their operation and cost. I remember back in '08 the fires in the pass between Nogales and Sierra Vista they had 5 of the single seaters and a Barron in and out of OLS. Talking to the guy who was running the show the number was astronomical to keep those planes in the air doing continuous drops. Granted there isn't much in terms of houses or major developments like the current fires in CA.
The costs are pretty high for 944 from what i understand, but that's expected. I believe it has to do a season or two as Call When Needed, before it can get an Exclusive Use contract. And even then, you can only fight fires on land that you're authorized to. For now, that's California for 944, state land; the USFS still hasn't authorized it's use on their lands. Stupid, I know. But there's bureaucracy.
