#100 Chris Hewlett, Project ULTRA: Why DoD will lead UAS integration

In this 100th episode, we sit down with Chris Hewlett, former Navy Commander and Director of Project Ultra, for a candid conversation about the realities of UAS integration. Chris challenges the industry’s rush toward community-based traffic management and questions whether UTM, as commonly envisioned, can ever deliver safe and scalable integration. He argues instead that the Department of Defense, through rigorous test, evaluation, and rapid operational deployment, will set the standard for comprehensive UAS integration - a framework that will ultimately spill over into commercial use.We cover the lessons from Project Ultra on verification, validation, and operational test and evaluation (OT&E) of unmanned systems, FAA’s Part 108, and why shortcuts and theory aren’t enough for safe airspace integration.

#99 Jia Xu, SkyGrid: Opening the sky for autonomous flight

In this episode, we welcome back Jia Xu, CEO of SkyGrid, to discuss the future of autonomy and shared airspace. SkyGrid is building a trusted airspace and operational integration platform to enable safe, secure, and efficient autonomous flight.Jia highlights where the main bottlenecks and complexities exist across autonomy, advanced air mobility, and shared airspace, and how the industry can move forward. We cover regulatory frameworks such as Part 108 and Part 146, the role of data services, and how SkyGrid is positioning its technology and products to help enable safer and more efficient aviation.

#98 Ryan Graves, ASA: UAPs as a wake-up call for airspace safety and innovation

Ryan Graves is a former U.S. Navy F/A-18F pilot and the first active-duty pilot to publicly report regular UAP sightings. In this episode, we explore what these encounters reveal about gaps in our airspace sensing and safety infrastructure, and where the opportunities lie for better detection, data analysis, and aerospace innovation. Ryan also shares insights from his work at Americans for Safe Aerospace and AIAA, where he’s helping bring scientific rigor and policy attention to a long-overlooked issue.

#97 Julie Garland, Avtrain: Drone business and regulation in Europe

In this episode we’re joined by Julie Garland, CEO of Avtrain, for a deep dive into the current state of the drone industry and regulation across Europe. Julie shares her perspective on why societal acceptance is just as critical as regulatory approval. We explore how operators like Manna are working to normalize drone activity and influence regulations, and why simplifying regulatory frameworks, including the SORA process, is essential to enable broader adoption of drone operations.The conversation also sheds light on the limited number of authorized SAIL III operations across EASA member states and the challenges operators face in meeting technical validation requirements, often by building their own aircraft. Julie walks us through promising commercial use cases, from consumer delivery to infrastructure inspection to airport operations, and outlines how digitization and standardization could unlock more scalable, efficient drone deployments. 

#96 Chad Sweet, ModalAI: Small, smarter, safer UAS - made in USA

In this episode, Chad Sweet, co-founder and CEO of ModalAI, joins us to explore the evolving drone landscape and what’s driving the next wave of innovation. Chad shares his perspective on the rising importance of FPV (first-person view) technology - especially in military and public safety applications - and why user experience, including ease of flight and high-quality video streaming, will be a key competitive edge going forward.We also dive into ModalAI’s strategic partnership with Qualcomm and the company’s focus on developing NDAA-compliant, AI-powered components that enable autonomy and advanced perception in small UAS. Chad offers insight into ModalAI’s product development philosophy and how the drone industry has matured over the past decade.
