Australian waterbomber helicopter dwarfed by huge wildfire

SYDNEY (Reuters) - Firefighters battling huge bushfires in Australia used a waterbombing helicopter to try and douse a blaze on the outskirts of Sydney on Thursday, with aerial footage showing the aircraft dwarfed by thick black and grey billowing smoke.

Officials in New South Wales (NSW) state declared the second state-wide emergency in as many months on Thursday as more than 100 fires burned across the state, more than half of them uncontrolled.
