does a propeller screw itself on air or is it just reaction

but if it is just a reaction thing why the propeller is not in the back ?

btw did you know that is accepted that one of the 3 newtons principles is just WRONG?

also do you know that if the plane is moving at 600kph and sending air backwards at 590 kph the air is actually being sent forward so the plane should move backwards ?

oh yeah you know it all and understand it all anybody who question things just inhales

i was told this when i started on engineering if you have no faith you have nothing to do, well im finishing now after 12 years

WHERE IS YOUR GOD NOW????
