Again like a video from Tucson it seems like it took an extraordinarly long time to get water on the fire! I also question whether the venting was actually freelance or if the firefighter was ordered to do it to make it easier for entry teams?
The way the fire took off they certainly didn't have water on it, to vent for life is ok but this looked premature to me, I was taught to vent when I heard the line being bled.
