Amazon Prime Air.

It sounds like an April Fools' joke, but this is totally real. Amazon just revealed a shock-inducing plan to get delivery times down to a mere 30 minutes by using an army of aerial drones.

We're excited to share Prime Air - something the team has been working on in our next generation R&D lab. The goal of this new delivery system is to get packages into customers' hands in 30 minutes or less using unmanned aerial vehicles. Putting Prime Air into commercial use will take some number of years as we advance technology and wait for the necessary FAA rules and regulations.
