Explores the research behind the rule, potential mitigation measures that might allow drones to fly over people and the potential impact to the commercial drone market. Episode #5 features an in-depth interview of Dave Arterburn, University of Alabama Huntsville who is Principal Investigator at ASSURE, the FAA's Center of Excellence for UAS Research. We explore small UAS impact studies, ground collision severity research, and what really happens when a drone strikes a person on the ground.
