    Plane on a treadmill always seems so obvious to me. Planes don’t have power connected to their wheels. Put a plane on a dynamometer and crank the engine up as fast as it will go, and the wheels will still not spin. At the same time, water planes use pontoons and are still able to take off just fine.

    The question I have is, can a plane take off with a tailwind that matches the speed that the propeller is pushing out.

    I wonder what percentage of these weird studies that make us ask “why are they spending money on that?” are being done by students working on theses and doctorates and whatnot, and what percentage are non-scholastic institutions asking for government funds to see if you can teach penguins to French kiss.
