Why Airlines Don't Fly Higher Than 40,000 Feet?
Commercial airplanes are incredible feats of engineering that transport millions of people every day. In this video, we explain why passenger airlines don't fly higher than 40,000 feet using real physics, aerodynamics, and aviation history. Why Planes Don't Fly Higher Than 40,000 Feet Explained | Simple Things Surprising Histories This documentary-style episode from Simple Things Surprising Histories covers the complete science behind commercial flight altitudes, from atmospheric pressure to the engineering limits of modern aircraft. Topics covered in this video: • Why 35,000 to 40,000 feet is the "Goldilocks Zone" for flight • How air density affects fuel efficiency and airplane drag • Why jet engines need specific oxygen levels to operate properly • The terrifying aerodynamic concept known as the "Coffin Corner" • How freezing temperatures and the speed of sound affect flight safety • The critical role of cabin pressurization for passenger survival • What "Time of Useful Consciousness" means at extreme altitudes • Historical exceptions like the Concorde and private business jets Chapters: 00:00 - Intro: The Invisible Highway 01:09 - Chapter 1: The Goldilocks Zone 02:13 - Chapter 2: The Coffin Corner 03:25 - Chapter 3: The Human Element 04:22 - Outro: The Exceptions and the Rule This video is designed for aviation enthusiasts, students, and general audiences who want a clear explanation of flight physics without unnecessary complexity. All explanations are factual, educational, and suitable for learning purposes.
