The PfCO course delivered by Airborne Platforms UK Ltd is excellent. It's a challenging and rewarding course. The theory modules are interesting, informative and helpful, and the practical modules, along with the guidance at tutorials and one to one meetings, are first rate. Chris Marshall's patience, helpfulness, expertise and attention to detail are stand-out features of this course. Drone flying at a commercial level is a serious business, fraught with challenges. The professional guidance, and the examples of risk mitigation that Chris and his team set will endure in the professional practices of course participants, and will make drone flying a safer, more professional, and more worthwhile activity.
