In this episode we speak with Lauren Flanagan, CEO of Sesame Solar, which builds mobile nanogrids. The product is a self-contained unit that generates its own power from solar, batteries, and stored hydrogen, set up by one person in fifteen minutes. The company started in emergency response and extreme weather, and has moved increasingly into defense. The newer focus, and the one we spent most of the episode on, is using these nanogrids to refuel hydrogen drones in the field. Most of the conv...

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 ...

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-overlo...

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 Q...

In this episode, we welcome back Brandon Suarez from Reliable Robotics, more than three years after his first appearance. Brandon leads the development of technical standards and global aviation policy, and this return visit offers a valuable perspective on how the aviation industry has evolved, and in some ways, diverged from expectations. The conversation centers on the implementation of automation in aviation and its operational and safety benefits, especially for general aviation. Brandon...

Welcome back to The Vertical Space for our second conversation with Richard Aboulafia, an insightful voice on all things aerospace and defense. This episode dives deeper than ever into the aerospace and defense supply chain: globalization, vulnerabilities, titanium, rare earth elements, and why Tier 1 integrators may be losing their place in the industry. We explore how shifting geopolitics, material dependencies, and evolving national strategies are redrawing the map of the aeros...

In this episode we sit down with Chris Gentile, General Manager for Tactical Autonomy at Merlin, for an in-depth look at the evolving role of autonomy in defense. Chris outlines the value proposition of autonomy as a tool, not a standalone product, and discusses the principles of a modular, hybrid, and hierarchical architecture design in building robust autonomous systems. We explore how recent milestones in trusted autonomy are reshaping military strategy and capability, and how the technolo...

In this episode, we sit down with Captain Donald Lee Moak, a distinguished aviation leader. With experience spanning military and commercial aviation to boardroom leadership, Lee is known for driving change. He doesn’t just talk about change; he makes it happen. Our discussion centers on three major themes: the urgent need to modernize and privatize the U.S. air traffic control (ATC) system to enhance safety and efficiency, lessons from aviation’s strong safety record, and the recent rise in ...
