The delivery drones are coming

When Amazon made public its plans to deliver packages by drone six years ago, many skeptics scoffed-including some at this magazine. It just didn't seem safe or practical to have tiny buzzing robotic aircraft crisscrossing the sky with Amazon orders. Today, views on the prospect of getting stuff swiftly whisked to you this way have shifted, in part because some packages are already being delivered by drone, including examples in Europe, Australia, and Africa, sometimes with life-saving consequences. In 2020, we should see such operations multiply, even in the strictly regulated skies over the United States.
