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.

"Current U.S. FAA regulations prevent ... using UAVs [Unmanned Aerial Vehicles,
like drones] for commercial purposes at the moment," Simpson said over Gchat.
"Honestly I think it's not totally unreasonable to regulate something as
potentially dangerous as having flying robots slinging tacos over people's heads
... [O]n the other hand, it's a little bit ironic that that's the case in a
country where you can be killed by drone with no judicial review."

It seemed too delicious. Too exciting. Too good to be true. And
that's because it was.

Tacocopter, a faux Silicon Valley start-up, threw the Internet for a loop these
last few days with a website that promised the delivery of tacos via unmanned
drone helicopters that accepted orders from a smartphone app.
