Episode notes
A Career Born From A Modding Pitch
- Ben planned to leave software to become an air traffic controller but stayed after contributing a file format and joining Laminar Research.
- That chance contribution turned into a 20+ year career on X-Plane.
Simulator Between Game And Platform
- X-Plane sits between AAA games and a platform because it must remain compatible with third-party content over decades.
- This forces conservative changes and prioritizes continuity over radical engine-driven art changes.
Domain-Specific Physics Over General Solvers
- X-Plane uses a domain-specific physics engine modeling airfoils and airflow rather than general game physics bricks.
- That lets emergent aerodynamic effects appear without expensive CFD for many design explorations.
