BTW, the rotor blades of a helicopter rotate one way in the northern hemisphere and the opposite way in the southern hemisphere due to the Coriolis Effect. This makes flying across the equator in a helicopter a bit tricky.
Some Fella-Like Person picked up on this and posted this comment...
“The usual approach is
for northern hemisphere helicopters to fly upside down when they cross the
equator into the southern hemisphere, in order to reduce the Coriolis Stress on
the pilots (*). The problem is a little simpler for dual rotor craft, e.g.
Osprey or Chinook, which merely have to fly backwards.
(*) The pilots
have to remember which way they flipped over when they
crossed into the Southern Hemisphere, because when they cross
back to the Northern Hemisphere it is
important to have a net winding number of zero.
If that isn’t done properly, then everyone on the aircraft who is
right handed will become left handed (and vice versa). There are
unsubstantiated rumors about the effects upon sexual preference, but
I’m not going to dignify them further.”
Ain’t that beautiful!

Lagniappe: Everyone knows that water going down a toilet spins Counter Clockwise in the Northern Hemisphere and Clockwise in the Southern Hemisphere. This is because of the Coriolis Effect. Hey, everyone, you are wrong...
There is an urban legend that water
in toilets spins in opposite directions in the Northern and Southern
Hemispheres because of the Coriolis Effect. But that isn't true—a toilet
bowl is too small for the effect to be observed. Instead, other factors like the
shape of the toilet bowl and the direction that the water enters are largely
responsible for how the flushing water moves.
