WELL, THIS IS THE 21ST CENTURY, YOU KNOW: In Major Step for Drone Delivery, Amazon Flies Package to Customer in England.

On Wednesday, Mr. Bezos announced on Twitter that his company had made its first commercial drone delivery, on Dec. 7, to an Amazon shopper in Cambridgeshire, England, a major step forward in its experiments with automated shipments.

The flight — to deliver an Amazon Fire streaming device and popcorn to a customer identified only as Richard B. — took off from a nearby Amazon warehouse and lasted 13 minutes, covering about two miles.

What will really impress is when Amazon introduces ballistic deliveries, like a long-range t-shirt cannon at football games.
