Does anyone know why planes fly? I counted 11 Theories of Flight and there doesn't seem to be any proof for any of these theories. Like a real experiment on a real aircraft using the scientific method? All I get is equations (Navier-Stokes) when i ask an engineer or professor; which isn't what we're taught at flying school. The official explanation of flight that pilots are taught is impossible and implausible. Even NASA thinks so (see "incorrect theories of flight?).
