How can an airplane be able to fly from west to east despite the Earth s rotation?

Dear readers, thank you for reading my article in your busy schedule, this is an affirmation of my efforts, but also the motivation to continue to create, I would like to extend my most sincere respect to you, I hope to get one of you"Attention"Thank you!

Today we are answering the questions of the fans again, and our next question is:

Hello. If we assume that the official science is correct, then the speed at which the Earth rotates around its axis is about 1600 km hours. At the same time, the average flight speed of the aircraft is 800 km h. So how does the plane fly from west to east?In the direction of rotation?Any sane person who agrees should come to the conclusion that orthodox science is somehow unable to break even.

Proponents of flatness often resort to this argument. From their point of view, since the Earth is moving faster than the plane, then it should fly away from under the Earth, so the plane cannot move forward, but must lag behind the Earth, so to speak, backwards. However, anyone who took to the skies saw with their own eyes that nothing like this happened. Based on this, levelists conclude that our planet does not actually rotate.

Before we begin to overturn this logic, we should review Newton's first law:

If there is no unbalanced force acting on the object, the object will remain at rest or in a uniform linear motion.

Let's consider the following scenario: a plane is parked on a runway somewhere at the equator. The Earth below it rotates at a speed of 1600 km/h, but at the same time the plane remains stationary with respect to the Earth's surface, therefore, it rotates around the Earth's axis at the same speed.

The plane began to accelerate, take off and move westward at a speed of 800 km/h. According to Newton's first law, the initial velocity of 1600 km-h that an airplane has while on Earth will not disappear anywhere, and the airplane will only add another -800 kmh to it (that is, it will slow down by 800 kmh).

From the point of view of a stationary observer located in the center of the Earth, the speed of the aircraft will be equal to 800 km/h (1600 kmh + 800 kmh), and it will be guided to the east, but for him, the Earth's surface will move eastward at a speed of 1600 km/h.

If we put an observer on the surface of the Earth, then he will not be able to see 1600 km h, because he himself is moving at such a speed together with the Earth. For him, the plane will move west at a speed of 800 km/h.

Now let's look at the situation where the plane takes off in the same way, but flies east at a speed of 800 km h. Newton's first law still remains in effect, and the initial velocity still does not disappear.

From the point of view of our stationary observer, the plane will fly eastward at a speed of 2400 kmh (1600 kmh + 800 kmh), but for an observer who is located on the Earth's surface and rotates with the Earth, the plane's speed will only be the same 800 kmh in the easterly direction.

Thus, we can conclude that the rotation of the earth does not have a significant effect on the ability of the aircraft to fly in one direction or the other, since during takeoff, the aircraft does not lose its rotational speed at takeoff. Standing on Earth.

Absolutely similar, if a person jumps, he will land at the same point;When he is in the air, the ground does not fly away from under him. This means that Isaac Newton was right when he formulated his first law.
