On the news this morning: Five helicopters will join the search for an ultralight plane carrying two men, which failed to return to a central Queensland airport. An Australian Search and Rescue Coordination Centre (AusSAR) spokeswoman says the plane left Emerald airport at 3pm (AEST) on Wednesday. The alarm was raised around 6.30pm (AEST) and a search conducted using night vision goggles and infrared equipment. "It was a pre-sale familiarisation flight," the spokeswoman told AAP on Thursday. "We are coordinating a search with five helicopters. "We are hoping a more intense daylight search may find something."
