How do airplanes stay in the air? - Raymond Adkins (2023x12)

:

By 1917, Albert Einstein had explained the relationship between space and time. But, that year, he designed a flawed airplane wing. His attempt was based on an incomplete theory of how flight works. Indeed, insufficient and inaccurate explanations still circulate today. So, where did Einstein go wrong? And how exactly do planes fly? Raymond Adkins explains the concept of aerodynamic lift.
