ALAN has shark teeth gouges in both legs. Gavin slipped while rock fishing and the eight- foot drop snapped both his ankles. Ivan collapsed in the middle of nowhere. Who ya’ gonna call? Those brave folk of the Westpac Rescue Helicopter Service, who swoop into places other paramedics can’t. Human drama ( and a little human stupidity) meets the harsh Aussie landscape and wildlife in a life- and- death half- hour narrated by Martin Sacks.
