The Vertical Space is a podcast at the intersection of technology and flight, featuring deep dives with innovators, early adopters, and industry leaders.

We talk about the radical impact that technology is creating as it disrupts flight, enabling new ways to access the vertical space to improve our lives - from small drones to large aircraft. Our guests are operators and innovators across the value chain: airframers, technologists, data and service providers, as well as end users.

  • #110 Mike Stengel, AeroDynamic Advisory: Gulf crisis impact on air travel
    May 6 2026

    We sat down with Mike Stengel of AeroDynamic Advisory to discuss what the US-Iran conflict is doing to aviation. The Middle East moves about 20% of global crude, and with the Strait of Hormuz closed and Gulf refining capacity damaged, jet fuel stocks in Asia-Pacific and Europe are drawing down while crack spreads widen in ways hedging contracts don't cover. Mike explains why US shale isn't the easy substitute, why Spirit just liquidated and JetBlue looks fragile, and why Delta's once-mocked Monroe refinery acquisition suddenly looks prescient.


    The bigger question we get into is whether this is a temporary pricing event or a more permanent regime change? For the first time in decades, commercial, military, and business aviation are all riding supply-constrained tailwinds at once, but the industry spent 30 years optimizing for cheap energy and stable airspace. We dig into what fragility looks like when those assumptions break, aging fleets, narrowing corridors between unusable Middle East and Russian airspace, what the conflict is doing for SAF, and where the next contrarian bet might come from.

  • #109 Admiral Phil Kenul: What flying into hurricanes taught him about drone regulation
    Apr 20 2026

    Admiral Phil Kenul spent decades flying NOAA aircraft into some of the most dangerous weather on earth, including multiple seasons as a P-3 Orion hurricane hunter, before transitioning into the world of UAS standards, where he now serves as Vice Chair of ASTM Committee F38. That path gives him a perspective on unmanned aviation that most people in the industry don't have. He's been the guy in the cockpit, the program manager trying to replace the cockpit with a Global Hawk, and now the person writing the standards that determine whether any of this scales commercially.

    His take on the industry is refreshing. Technology, he argues, is no longer what's holding the drone industry back. Operations, regulatory approvals, and integration with legacy airspace systems are. He sees Part 108 as a genuine inflection point, one that will finally let operators fly by regulations and industry consensus standards rather than one-off waivers. But he's equally clear that getting there will take longer and cost more than most people expect, and that when the dust settles, success will go to the best operators, not the best aircraft.

  • #108 Alex List, FlyShirley: 'Shirley' there's an opportunity for AI in the flight deck
    Mar 17 2026

    In this episode we sit down with Alex List, CEO and founder of FlyShirley, a startup building an AI copilot for the cockpit. Alex walks through what AI in aviation actually looks like today: the practical reality of a ground-based language model accessed via iPad helping pilots handle strategic, non-time-critical tasks like looking up service bulletins mid-flight, transcribing ATC clearances, finding alternates, and synthesizing information that would otherwise require a pilot to dig through a POH while managing weather and workload. He's candid about where the technology still falls short and articulates a clear architectural thesis: frontier intelligence lives on the ground, state management lives on the device, and a 56-kilobit connection is all you need in between.

    The conversation broadens into the harder questions facing anyone building in this space: how do you design for pilot augmentation without creating dependency? How do you handle liability for an advisory system that is occasionally wrong? And how do you build a defensible business in a market that is, honestly, pretty small? Alex is refreshingly honest about the GA market math and where the real opportunity lies. The hosts bring their own investor and operator lens to the discussion, flagging the classic failure modes of aviation startups.
