    proof for how planes fly??

    The book: “UNDERSTANDING FLIGHT” by Anderson & Eberhardt (2010) confirms the core ideas of the dynamic buoyancy argument. Cahpter 1: “ ..... lift is generated by the wing diverting air down .....” “...... the lift of a wing is proportional to the amount of air diverted (down). “...

    speed boats rise upwards in the water when they pick up speed.

    proof for how planes fly??

    OK; thanks for the responses - this is similar to what I hear elsewhere. Let me try something new: Planes fly for the same physics as why boats float; buoyancy. By pushing air (or water) downwards equal to their own mass. Same as why birds fly. I haven't heard this anywhere else before, but no...

    proof for how planes fly??

    sure you can do an experiment using the scientific method. OK, it's now 13 theories for how planes fly if you include "magic" and "headset voices"

    proof for how planes fly??

    The problem is that navier-stokes is just an equation; is describes flight, it doesn't explain the physics.

    proof for how planes fly??

    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...
