The Allplane Podcast #128 with Otto Aviation COO Scott Drennan

In this episode of the podcast we’ll explore one of the most truly disruptive clean-sheet aircraft projects currently underway.

Scott Drennan is President and Chief Operations Officer (COO) of Otto Aviation, a US startup aircraft maker that is developing an ultra-efficient executive jet. The Phantom 3500 uses a teardrop-shaped design to take full advantage of the laminar flow principle and reduce drag to a minimum.

Otto Aviation is, in fact, not a newcomer. The firm has been working on this concept for more than a decade, although in the last few years it has pivoted from the original idea, the Celera 500L propeller aircraft for the general aviation market, to the Phantom 3500, a fully-fledged business jet which aims to compete in the super-mid-size category of business jets.

With Scott we talk about Otto Aviation’s disruptive approach to aircraft design, how laminar flow can be mastered to achieve some unprecedented fuel efficiency gains and what this involves in terms of financial and environmental performance. We also touch upon one of the most eye-catching features of the Phantom 3500: the absence of windows for extra aerodynamical gains and how Otto Aviation is responding with a new way to conceive the passenger experience.

And, following the announcement, made during the 2025 Paris Air Show, that Otto Aviation is investing in a greenfield manufacturing facility in Jacksonville, Florida, we also discuss the company’s investment plans and go-to-market strategy. How many aircraft is it planning to build per year? Who is it planning to primarily compete with and how?

Tune in for a fascinating conversation that combines technical and commercial insights about the unique Phantom 3500 business jet, a flying bullet which may change how we think about aerodynamics and aircraft construction!
