Amazon on Sunday shared an update on its drone-delivery service, which was first introduced in 2013 with a teaser that many thought was a joke.

On a newly updated Amazon Prime Air landing page, Amazon shares an updated Prime Air drone design: The new Amazon Prime Air drone-delivery prototype. Amazon

Alongside that update goes a pair of new videos, one starring controversial former "Top Gear" star and recent Amazon Studios employee Jeremy Clarkson, detailing what Amazon Prime Air will be like in real life.

That includes some sweet footage of the drone grabbing a package and taking flight:

The eventual goal is to deliver packages weighing 5 pounds or less within half an hour. Amazon vice president of Prime Air Gur Kimchi was quoted earlier this year as saying, "Prime Air is trying to get as close as possible to real teleportation — without breaking the laws of physics."

And in a FAQ section on the Amazon Prime Air website, Amazon reassures customers that far from science fiction, this is very real.

"One day, seeing Prime Air vehicles will be as normal as seeing mail trucks on the road," Amazon writes.

Amazon also says that this isn't the final design for Prime Air and that the retailer is testing as many as a dozen different design prototypes intended for different uses. As TechCrunch notes, the drone design revealed Sunday is much larger than previous prototypes we've seen:

The drones are being developed in research centers in the United States, the United Kingdom, and Israel, Amazon says. Recently, Amazon CEO Jeff Bezos said the UK was a likely candidate for being one of the first places to start seeing Amazon Prime Air drones take flight.
