The day three men in a tugboat prevented a disaster

On Monday, three men embarked on a perilous journey to stop a catastrophe from unfolding on Sydney's shoreline. On a tugboat, in 9 metre swells, they worked for hours to prevent a cargo ship carrying fuel from ploughing into a cliff, saving the lives of 21 crew members and averting an ecological disaster. Today we talk to those men about their extraordinary rescue mission. Featured: Brad Lucas, tugboat captain Marius Fenger, engineer Alex Alsop, deckhand
