Fact 4: The conveyer, as it moves faster, exerts more and more backwards force upon the wheels, and this force is not inconsequential.
Could you please give us the equation for frictional force as a function of relative speed? Because all of the models for dry friction with which I'm familiar have the force being approximately constant with speed. In other words, it's possible to construct a system such that the frictional force would be enough to prevent the plane from taking off, but such an airplane wouldn't be able to take off from a normal runway, either.
