In this episode of Hangar X Studios, host John Ramstead welcomes Dave Merrill, the visionary co-founder of Elroy Air, to explore how a personal passion for photography and drones evolved into building one of the world’s largest and most innovative autonomous cargo aircraft. Merrill recounts the journey from idea to implementation of Elroy Air’s flagship vehicle, the Chaparral, a hybrid-electric VTOL drone capable of delivering hundreds of pounds of cargo over long distances — autonomously.

We unpack how the team navigated early skepticism, technical challenges, military collaborations, and humanitarian partnerships to turn Elroy Air into a $2 billion demand operation. From securing support from SHIELD Capital and the Defense Innovation Unit to designing autonomous logistics for both military and commercial customers, this episode is a deep dive into the future of aviation logistics.
