This roundtable discussion from the Transport Security International magazine explores the growing threat of drones to airport airspace and the ways in which this threat can be countered. Experts from D-Fend Solutions and Echodyne discuss the increasing number of incidents involving drones near airports, the various motives behind these incidents, and the current and future technologies available for detecting, tracking, and mitigating drone threats. The discussion highlights the need for a comprehensive approach to airport security that incorporates both passive detection and active mitigation strategies, as well as the importance of developing technologies that can distinguish between authorised and rogue drones.
