ManaAdaSystem, there is no confirmed information that the response took five minutes, nonetheless does your home airport have two 4km long runways? Is response time from dispatch to arrival at the fire scene or getting to work in a genuine emergency (not putting foam onto a practice hull in a known location)? And has it been tested in a real emergency? When the Asiana incident occurred there was a lot of criticism on this forum of imprudent fireground appliance management. The biggest mistake firefighters can make is rushing into a fire.
