But, are these building moving at 200 kts, or more, having all that extinguishant sucked out at the same time?
and lots of extinguishers to get the extinguishant to the right places in the right time.
"Lots". Thats not a qualified answer. I'm sure that a fire extinguisher company in the avaition field will have computer models that will take into account the volume, the atmospheric pressure, the class of fire and the unavoidable rate of leakage of the extinguishant from the container, etc.
