Seems like the thread on "why pull back to go up" was so popular, let's try this one: why do aircraft engines turn clockwise (as seen from the cockpit)? And to stir further controversy, why do Aerospatiale helicopter rotors turn opposite from almost every other helicopter?. Specifically excluded from this discussion are P-38 Lightnings and CH-46 and CH-47 helicopters, and the Flying Banana, whatever it's designation was. FO'ARD, HAARCH !!!!!!
