Newton may have had a theory at one point in time but now he has a law, in fact three of them. When I quote Newton, I'm not doing it through anyone's intermediation (eg 407too's post), nor am I supporting a Newtonian theory of lift (whatever that might be). I'm simply setting out what his insights offer by explaining lift as a reaction to air being accelerated downwards.
From a pilot teaching perspective it's perfect, because it builds on existing universal knowledge (rockets, pool tables, school physics), and avoids the pitfalls of other approaches by leaving the mechanism out of it.
If other people have chosen to bend Newton to their aims as many have tried with Bernoulli, then good luck to them, but they're nothing to do with me other than standing on the shoulders of the same giants.
