Walmart is starting to deliver at-home COVID-19 tests by drone. A trial got underway in North Las Vegas today and the deliveries will expand to Cheektowaga, New York early next month.

It’s delivering the kits to qualifying patients who live within a mile of certain Walmart Supercenters in both locales. Patients will self-administer a nasal swab, which they’ll send to Quest Diagnostics for testing.

The Federal Aviation Administration has granted Wing an expanded Air Carrier Certificate. It has permission to “allow multiple pilots to oversee multiple unmanned aircraft making commercial deliveries simultaneously to the general public.” UPS also received FAA certification for commercial deliveries this month, but it will stick to hospitals and medical campuses for now.

Folks in Christiansburg can order goods from Walgreens or Sugar Magnolia through the Wing app, and a drone will drop off their order to a pre-determined location in their yard or driveway. They can also opt in to have FedEx Express deliveries made by drone. The trial follows other Wing pilot projects in Australia and Finland.

Flight Forward is the first company to claim the Part 135 Standard certification, and it’ll be able to operate an unlimited number of drones. The machines and their payloads can weigh more than 55 pounds and UPS can fly its drones at night.

Earlier this year, under the Transportation Department’s Unmanned Aircraft Systems Integration Pilot Program, Flight Forward started transporting medical lab samples and blood for transfusions around WakeMed’s healthcare campus in Raleigh, North Carolina. After it received the FAA certification, it launched a Matternet M2 quadcopter flight under a “beyond visual line of sight” (BVLOS) exemption, which it says was “a first in the US for a regular revenue-generating delivery.”

At first, UPS plans to expand drone deliveries to hospitals and medical campuses across the US. It’s also planning to carry out flights outside of the healthcare industry, “including the transport of special commodities and other regulated goods.”

It aims to build a centralized operations center, run regular BVLOS flights and work with manufacturers to build drones that can carry various capacities of cargo. UPS also plans to quickly build out ground-based, detect-and-avoid technologies for safety and to expand its service in the future.

“This is history in the making, and we aren’t done yet,” UPS CEO David Abney said in a statement. “Our technology is opening doors for UPS and solving problems in unique ways for our customers. We will soon announce other steps to build out our infrastructure, expand services for healthcare customers and put drones to new uses in the future.”
