Amazon’s Flying Warehouse Idea Isn’t Even Its Biggest Challenge:

"Delivering packages by drone at all seemed at first like “a loopy idea, far-fetched and the subject of instant mockery on Twitter,” as New York Times technology writer David Streitfeld wrote when Amazon CEO Jeff Bezos first mentioned it in 2013.

Now it’s considered all but a certainty, even if the timeline is hazy. Other companies are exploring or testing drone package delivery, including Google, Walmart and the United Parcel Service.

Amazon holds a separate patent for a system of light poles that would serve as miniature drone docking stations. There’s no indication it’s any more viable than airships, but it seems to show a company rigorously exploring drone delivery from every angle.

Considering how the company’s other out-there ideas have worked out ― like entirely upending the publishing industry ― it’s safe to say it’s too early to write off flying warehouses."
