Indeed, the concept behind Tacocopter is very simple, and very American: You order tacos on your smartphone and also beam in your GPS location information. Your order — and your location — are transmitted to an unmanned drone helicopter (grounded, near the kitchen where the tacos are made), and the tacocopter is then sent out with your food to find you and deliver your tacos to wherever you’re standing.

You pay online, so the tacos are simply dropped off at your feet by the drone helicopter, which then flies back to the restaurant to pick up its next order…

Well, put down your smartphones, because here comes some bad news: The launch of Tacocopter — which is totally real, by the way, despite some doubters, and has been around since July 2011 — is being blocked by the U.S. government.
