Full disclosure- I am a retired wild land firefighter who worked on a helicopter crew in Southern California in the 80s and 90s. I was also an instructor at the forest service fire academy.
I just realized your confused about the origin of a fire, and the cause of the fire. Origin is only used in the phrase-“point of origin”. That’s what I’m talking about with the first year firefighter. The point of origin is not tricky at all. You think I meant cause. I said, I’m not speculating on cause, I already know the cause. I hop this makes you not so confused and gets you back in the convo, but then again, you don’t care,.. haha😅😂🤣😂
