The direction water goes down a drain has absolutely nothing to do with which hemisphere you are in. That is a fairy tale and has been completely debunked.
You think a sniper has to take Earth's rotation into account when firing a long range shot, but airplanes going thousands of miles do not have to adjust for this?
Quoting: Anonymous Coward 75901873 Can somebody finally settle this question: Does water flowing down a drain spin in different directions depending on which hemisphere you're in? And if so, why? Brad Hanson, a staff geologist with the Louisiana Geological Survey, presents the argument of why--in theory--water going down the drain would indeed spin in different directions depending on which hemisphere you're in. [ link to www.scientificamerican.com (secure)] Key words in your little copy and paste job are "in theory". In reality we do not see this. How can an airplane take off at the equator which is supposedly travelling at 1000 miles per hour and land in the North or South where the rotational speed is far less? The airplane has to take that inertia of the spinning globe with it when it leaves the ground, right? It would be impossible to fly West to East if it didn't. So how do planes land on runways facing opposite directions spinning at different speeds? There is also the issue of planes flying level and not adjusting for curvature. Just to put it in perspective a plane flying 500 miles per hour would have to account for 31 miles of curvature in that 500 miles. That's a half mile per minute the plane would have to dip down during flight to maintain it's altitude above sea level. I've been on many an airplane and you can really feel the plane's motion if it is ascending or descending. Do you think airplanes fly through the air in a continuous curve? People have taken spirit levels on planes and guess what? When the plane reaches altitude and levels off it does exactly that and the water in the level doesn't lie. An airplane works with lift opposing gravity. If the direction of gravity changes (as it would gradually do as it flies over the curved earth) then the aircraft would automatically orient itself with no input needed. What about taking off and landing in locations where Earths rotational speed is hundreds of miles per hour different? Gravity can't help with that too, can it?
