UPS, which received official US approval for drone deliveries last week, said it would quickly expand the use of the airbone delivery technology. The logistics group said hospital campuses, which often require fast delivery of medical supplies, are a key target area for drone deliveries. But it also cited many other potential business applications. “We aren’t done yet,” UPS CEO David Abney said in a press release. “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.”
