With an almost eagle-eye-view of the Rocky Mountains from his office in Denver, Robert Attai advises clients on the emerging field of unmanned aircraft systems (UAS), otherwise known as drones. A partner in the law firm of Husch Blackwell, his clients sometime seek advice after acquiring a smaller firm that is using UAS in their operations. Other times, a manager in the field starts using UAS without running it by headquarters first, leaving the company open to legal complications. Despite much of the legal confusion surrounding the use of UAS, Attai’s message is clear: without prior permission by the FAA, commercial use of drones is still illegal. That, however, is not the end of the story.
