Unmanned aircraft systems, commonly known as drones, are becoming a game-changer in modern logistics. They’re being used to deliver everything from medicine and food to groceries and homecare products. Their growing popularity in last-mile delivery is because of being more accurate, eco-friendly, and faster than traditional methods—all while cutting operational costs by up to 70%. The COVID-19 pandemic has made the application of this safe, contactless delivery model happen even faster.

Despite their speed and convenience, however, drones still face some significant challenges. One major concern is airspace management. The skies above urban areas are already too packed with planes and helicopters to add hundreds or even thousands more of delivery drones. Companies will therefore need to ensure these drones won’t threaten public safety or private property. Another problem is security. Since the drones will be traveling independently, their control systems have to be well-protected from hackers. A drone controlled by a hacker could pose serious risks to people, buildings, and other aircraft. And what happens when a malfunctioning drone falls from the sky? Obviously, these risks must be addressed properly before drones can become a mainstream delivery solution.
