AIRPLANES Shouldn't Be Able to Fly and Nobody Really Knows Why

You were taught how airplane wings create lift. Curved top, flat bottom, faster air, lower pressure. It's neat, logical, and satisfying. There's just one problem — it's completely wrong. The "Equal Transit Time" theory can't explain paper airplanes, symmetric wings, or inverted flight. So what's actually holding a 300,000-pound aircraft in the sky? In this video, we explore the physics of aerodynamic lift through a lecture inspired by Richard Feynman's legendary teaching style, drawing on foundational ideas from The Feynman Lectures on Physics (Volume II, Chapters 40–41 on fluid dynamics) and the broader tradition of rigorous yet accessible physics education Feynman championed. 📚 SOURCES: Richard Feynman, Robert Leighton, Matthew Sands — The Feynman Lectures on Physics, Volume II (1964), Chapters 40–41: Flow of Dry Water, Flow of Wet Water NASA Glenn Research Center — "Incorrect Lift Theory" and "Bernoulli and Newton" educational resources Graham Wild — "On the Origins and Relevance of the Equal Transit Time Fallacy to Explain Lift," arXiv (2021) Holger Babinsky — "How Do Wings Work?"
