Depends upon what kind of Fire you are fighting and at what stage of the fire you are deployed.
You ever seen a for real Forest Fire when it is Crowning and really blowing up?
When that happens the biggest helicopter might as well be a guy with a Piss Pump(jargon for a hand pump back pack water apparatus) for what good you really do.:uhh:
