UPS might soon be dropping off packages across the US by drone. The Federal Aviation Administration granted the UPS Flight Forward subsidiary air carrier and operator certification, allowing it to use drones for commercial deliveries. 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.
