    How do airplanes fly? The popular explanation for lift is based on Bernoulli's principle. This explanation fails to explain inverted flight or flat wings. So how do planes really fly? A great paper for your holidays reading list 📚🎁 Get it here: https://fermatslibrary.com/s/how-airplanes-fly-a-physical-description-of-lift …pic.twitter.com/WQnEMDrHlS

        Twitter censors the video as "potentially sensitive content". I suspect the AI might have confused the two turbulent vortices for human breasts.

        'It’s all to do with the harsh realities of physics up in the sky; it’s power-to-weight ratios, it’s wing cross-sections, wing surface-areas, it’s practical aerodynamics! It’s also cold and extremely windy!' Adams, D. N., 1980 (@TravisinaB7 😉)

        The principle of flight was revealed by Günter Propftt (1683-1765) in a paper published in “Annalen der Flügmeisters” in 1721. Airplanes fly because their power of flyness overcomes the power of EarthSuck (formula: f>ES). He also predicted exit rows and little bags of pretzels.

        Bernoulli’s principle optimizes right side up level flight. But the “kite” effect enables inverted flight.
