Below is the pertinent part of what the National Geographic website had to say in September 2015 about the Coriolis effect.
"Fast-moving objects such as airplanes and rockets are influenced by the Coriolis effect. Pilots must take the Earth’s rotation into account when charting flights over long distances. This means most planes are not flown in straight lines, even if the airports are directly across the continent from each other. The line between Portland, Maine, and Portland, Oregon, for instance, is very long, and fairly straight. However, a plane flying from Portland, Oregon, could not fly in a straight line and land in Portland, Maine. Flying east, the Coriolis effect seems to bend to the right, in a southerly direction. If the Oregon pilot flew in a straight line, the plane would end up near New York or Pennsylvania."

I was answering an email question today and checked the National Geographic website for that quote and, lo-and-behold, it was redacted from the website.
This is a link from the Way Back Machine from showing the original quote as it appeared on May 22, 2016: https://web.archive.org/web/20160522173257/https://www.nationalgeographic.org/encyclopedia/coriolis-effect/
Why would the National Geographic redact that example of the Coriolis effect? Because there is an obvious problem with the West-East example that they used to illustrate the mythology of the Coriolis effect on the supposed spinning earth. I pointed out that problem in my 2016 book, The Greatest Lie on Earth.
In my book, I wrote in pertinent part:
"The Coriolis effect is supposed to be based upon the spin of the earth and the fact that objects in motion over the spinning earth are moving independent of the spin of the earth once they are in motion. If there truly were a Coriolis effect on earth, it would pose a real problem for plane flights. If a plane were to take off from an airport in Portland, Oregon, in a North/South runway and turned east to fly to Portland, Maine, the airplane would never make it to Portland, Maine. That is because the airplane would be traveling at approximately 560 miles per hour once it reached cruising altitude. The earth, however, would be spinning at 700 miles per hour eastbound beneath the airplane. The airplane would never be able to catch up with the speed of the earth’s spin. The airplane would be constantly losing distance over the ground at the rate of 140 miles per hour. Essentially the airplane would be moving backward over the ground."
The National Geographic screwed up in its example. They did not realize when posting their example that if there was a Coriolis effect from the spinning earth it would make a transatlantic West to East flight across the United States impossible. The National Geographic knows that there is no accounting by aircraft pilots for a Coriolis effect. Their example is provably false; it is impeached by reality, so they removed it.
