Drones could soon be used to deliver medical supplies as a project challenges local authorities to generate ideas on how the gadgets can be used as more than toys. The Flying High Challenge aims to put the machines to use in ways that benefit cities, such as providing rapid response in floods and fires or monitoring pollution. Government agency Innovate UK has teamed up with London technology charity Nesta to explore five suggestions at how drones could operate in urban environments. A drone arrives at the King's College Hospital helipad in South London to demonstrate the delivery of medical supplies The technology could be used to transport blood, provide rescue assistance for police and carrying out risk assessments of critical infrastructure. Executive director of Nesta's Challenge Prize Centre Tris Dyson said the technology must be harnessed in a way that benefits communities on a local level.
