useful reading in relation to the Coanda / Magnus effects and their applicability to light aircraft. It's written by a physics PhD who presumably has a reasonable grasp of these things.
Unfortunately, if I understood correctly, his explanation is of how they are NOT relevant to the operation of light aircraft, rather than the other way around. Still, it's a very interesting read.
