Part 8/15:
Both sides discuss real-world observations like airplane routes and oceanic circumnavigation. Wit It highlights that direct flights exist between places like Sydney and South America, ostensibly challenging Flat Earth claims that such routes are impossible or would take longer paths.
Dave responds by explaining that flight paths are optimized based on Earth's curvature and atmospheric physics, not flat maps. Flat Earth advocates argue that the flight times and paths contradict the globe model, but Dave counters with data showing that flights take “great circle” routes that are predicted precisely by a spherical Earth.
