Amazon's drone delivery hasn't taken flight

"Jeff Bezos boldly predicted five years ago that drones would be carrying Amazon packages to people's doorsteps by now. Amazon customers are still waiting," AP's David Koenig and Joseph Pisani report.

The big picture: "[O]vercoming the regulatory hurdles and safety issues posed by drones" has been a bigger challenge than expected. "The day may not be far off when drones will carry medicine to people in rural or remote areas, but the marketing hype around instant delivery of consumer goods looks more and more like ... hype. Drones have a short battery life, and privacy concerns can be a hindrance, too."
