Well let's just say your right for !!!!!s and giggles.
Does the amount of "thrust" provided from the winglets amount to anything that you can chart vs. what the engines are producing or is it so small it is like hitching an ant up to your car and telling it to pull you to the grocery store?
Just got off the phone with somebody that wants to remain nameless, but I can say they market the winglets for Boeing products and also happens to be the owner of the company.....
He says the only way a winglet produces thrust is if they flap and flapping winglets have a very limited fatigue life!
