Griffon rotates the opposite way to the Merlin.
As to the man walking into the prop of the Aero Commander, on the C152 the wing strut would tend to prevent that a bit, but the new 162 sadly has the strut behind the door, which in my eyes is an accident in the making.
AS for some of the Gas Turbs, well a lot of them go both ways, as in the HP/ LP compressor rotations to counteract the rotational forces.
Damn u beat me to it as I typed !!
