While it’s become abundantly clear that Amazon faces regulatory challenges to offering drone delivery, a newly surfaced piece of information reveals just how difficult the road ahead will be for the online retailer.

According to the Washington Post, the promotional video for Amazon’s PrimeAir service — which aired on 60 Minutes and was posted online — wasn’t shot in the U.S., because FAA regulations regarding drones would have prohibited Amazon from doing so legally.

It’s not clear where exactly the video was shot — does anyone out there recognize the scenery? — but wherever it was, it didn’t take place on the company’s home turf.

It’s a clear reminder of the challenges the Seattle-based retailer will face before it can even get its experimental delivery program off the ground. While Amazon says that it’ll be ready to fly come 2015, that estimate counts on the FAA creating a regulatory system that allows Amazon to take to the skies.

While Amazon isn’t the only company with designs on drone delivery, it’s sure to be a contentious issue, given drones’ ability to intrude on others’ privacy, without necessarily jeopardizing the operator.
