Beyond Line of Sight: The Infrastructure Drones Need to Fly

From the Travel Tech Podcast newsletter for episode 2, Beyond Line of Sight: The Infrastructure Drones Need to Fly.

Listen to the episode here.

In this episode, I sit down with James Dunthorne, founder of Neuron Innovations and 4DSKY, and an all-round expert in drones, data, and aviation technology. We dig into his fascinating journey from studying for a PhD in aeronautical engineering to developing innovative solutions for drone operations. James connects his early research on collision avoidance, airspace safety limits, and sensor fusion to real-world deployments across agriculture, rail, and high-precision surveying, including complex projects like the restoration of the House of Parliament.

As our conversation unfolds, James explains why beyond visual line of sight (BVLOS) remains constrained by surveillance infrastructure, detection physics, and regulatory confidence rather than aircraft capability. We examine the technical and regulatory bottlenecks in depth, from fragmented transponder ecosystems and non-cooperative traffic to strict latency and reliability requirements in mixed airspace. The result is a credible path toward scalable, regulator-ready drone operations, and a broader physical-world data layer with implications well beyond aviation.

Key takeaways

• BVLOS as an Infrastructure Constraint
• Limits of Visual Airspace Safety
• Transponder Fragmentation at Low Altitude
• Edge Networks for Safety-Critical Systems
• Physical Infrastructure as an AI Enabler

We hope you enjoy the conversation.
