at this stage, the emotions are sort of starting, a bit heavy in there, we're trying to stay calm but we're sort of panicking. if we went back to help these guys we would've put ourselves in danger and more than likely would've been suffocated. we came up with a plan that, when it was safe to exit, we were going to all get out and put our breathing equipment on and we knew that the safest way for us to get out at that moment was to walk a kilometre back to safety would be a quicker, safer option than sitting tight in our burning truck, waiting for assistance to come to us. so we got out, we put our breathing equipment on. all four of us were safe at this point and uninjured and we were able to make the walk out. all the firefighters survived to bear witness to their extraordinary escape. but across australia nine of their colleagues died trying to save others from the fire.
