Kroger, one of the largest U.S. grocery store chains, has partnered with Drone Express to begin testing grocery delivery via autonomous drones.

Drone Express will commence test flights near the Kroger Marketplace in Centerville, Ohio. The flights will be managed by licensed drone pilots from an on-site trailer with additional off-site monitoring, per FAA regulation.

Customer deliveries are scheduled to begin later this spring, and a second pilot is scheduled to launch this summer at a Ralphs in California.
