Singapore leads move to publish guidelines for flying taxis, drones in Asia

Singapore is leading a move to write a set of guidelines for flying taxis and drones in Asia. Industry players said this marks a major milestone for more widespread use of such technology. It could also help more companies enter the market to provide services, like drone deliveries for food and medicine. The reference materials will be published in July before being submitted to the International Civil Aviation Organization in September. Nicolas Ng reports.
