Aircraft maker Boeing says it has built the first helicopter that can take off and land without the help from a human. The Unmanned Little Bird helicopter uses a rotating laser scanner on its nose, which pulls in detailed real-time data on what's ahead and what's below the helicopter. Other companies have developed similar helicopters before, but they've been only for use in the military. Boeing's innovation could potentially be useful for more efficient rescue operations and cargo transportation.
