Why do most American made jet engines, helicopters and prop driven planes have their fans, props and rotors turning anticlockwise when viewed from the front (jet engines and plane propellers) and from the top (helicopters), whereas the fans, props and rotors of European ones turn clockwise?

Question

I know there are exceptions like the General Electric GEnx fan turning clockwise despite being an American made jet engine.

Answer 1

It’s the Coriolis effect. If they changed the rotation of the jets so they all rotated in the same direction, toilets around the world would spin out of control. Trust me bro.
