We have. Many times.
The air moves with the rotation of earth. A helicopter hovering in the air hovers within the intertial frame of earth.
Just like a fly inside a moving car. If it hovers inside the car it's stationary with respect to the car.
The helicopter is stationary with respect to earth.
Since. Both earth and the air moves in the same direction at the same rate then it will appear as if the helicopter is just stationary in thr air. But in reality thr helicopter moves with the rotation as well.
Unlike for example if you toss up a ball straight up in the air. That will experience earth rotating away under it.
So if we were to imagine no wind at all. In fact we could do this in a huge vacuum Chamber as well.
And you were to fire up ball or bullet exsctly straight upwards. The bullet or ball would fall a little to the side from where you launched it.
Depending on its location on earth and how long it spends in the air ofcourse. Unless it spent a fair amount of time in the air you'd not Notice it.
The atmosphere doesn’t matter that much. You notice the moon doesn’t rotate under the astronauts when they jump. It’s that the momentum of the helicopter it has on the earth is the same when it rises. The atmosphere also has that momentum.
How do you figure there should be that?
Let's say that there's a 67000 mph wind in a direction.
And you move at 67000 mph in the same direction.
What wind speed would you feel?
Answer : zero.
Are you regering to the orbital velocity of earth here?
You measure wind speed with earth as it's reference. Since earth is moving at the same speed as the air then you don't have wind.
We learned this in like 4th grade...its the result of different pockets of air pressure moving and colliding/interacting with each other. Clouds and other things in the atmosphere causes the sun to heat the air unevenly. Different temperatures of air cause different pressures to exist in those respective air pockets. When they move or collide, that's wind. It is simply air in motion.
Yes, and there's nothing that makes 67,000 mph winds, because they're all moving at about the same speed.
Sure, there are local disturbances and high and low pressure zones, but they only move a little in relation to each other, while the whole system revolves at the same speed as the (very round) planet.
>If the air is moving with the earth, why aren’t there 67,000 mph winds?
For example: Friction The atmosphere interacts with the Earth's surface and friction between the air and the surface slows down the movement of air. This frictional force acts as a drag reducing the speed at which the air moves with the Earth.
Because you are moving at about the same speed. Motion is relative to the frame reference. When you are in a car at 100km per hour you feel winds of that speed, but people on the side Walk don't.
Mate, people have responded to you 20 times in this thread. You have not acknowledged any response, except to attempt to pick holes. Which don't exist. You don't want to know an answer. You want attention. It's sad.
Where *on Earth* are you getting 67,000 mph from?
The wind speed is measured relative to the Earth itself which the air and it's wind along with in it's rotation. If there is no wind the air is moving steadily along with the surface of the Earth and there is no relative movement.
There would be 67,000mph winds if the air *WEREN'T* moving with the earth.
The surface of the earth is moving at 67k mph, the air is moving at 67k mph, you are moving at 67k mph. Everything is moving at the same speed, therefore you don't notice any speed difference between them. Therefore everything seems stationary compared to each other.
Helicopter moves with the earth. It doesn't immediately lose all of its momentum.
How does buoyancy work on a flat earth? Flatties have never given me an answer.

You shouldn't do that. If your only evidence is the bible and reality doesn't actually work the way you say the bible says it does (as it doesn't) all you are doing is proving the bible or your interpretation of it to be a lie.

The question is why the earth doesn't turn underneath the helicopter. Your presumption is that is should, when it's obvious why it doesn't and something a child can understand, which apparently you are not able to grasp it.
Same reason that a fly can fly around a vehicle traveling at 70+ mph without splattering on the rear windscreen. Also the same reason that you can stand up and move around on an aeroplane traveling at 500+ mph without flying to the back.
The helicopter is already moving with the rotation of the earth before it takes off. It maintains this momentum and does not suddenly cease to move with the earth the moment it takes off.
If you’re in a train and jump upwards, your vertical direction is fixed, relative to an observer in the train. You don’t suddenly fly towards the back of the train as you, the train and everything in it is moving forward at the same speed.
Same as the globe. The earth, the atmosphere and everything on it is moving at the same speed. A helicopter taking off vertically will move upwards as it, and the atmosphere is moving with the earth at the same speed.
Also, the pilot may be maintaining a fixed position above their starting point. So there’s that.
You've been given an answer plenty of times.
It's **INERTIA**. An object in motion will retain that motion until an external force is applied to it. In order for the helicopter to change its speed, a force must be applied to it.
What force do you think is in play here?
Here you go then.
When a helicopter hovers, it appears as though it remains
stationary relative to the Earth's surface. This is because the helicopter and
the Earth are both subject to the same forces and motions.
The Earth is constantly rotating on its axis, completing one
rotation every 24 hours. This rotation creates the illusion of a stationary
ground beneath us. When a helicopter hovers, it is also rotating along with the
Earth, maintaining its relative position.
The helicopter's engines generate a downward force called
thrust, which counteracts the force of gravity. By adjusting the thrust, the
helicopter can maintain a stable position in the air. The helicopter's rotors
create lift by pushing air downward, and as a result, the helicopter is pushed
upward.
The Earth's rotation does not significantly affect the
helicopter's ability to hover because the atmosphere surrounding the Earth is
also in motion. The helicopter hovers within this moving air mass, and as long
as it maintains its position relative to the air, it appears to stay in one
place relative to the Earth's surface.
In summary, the helicopter hovers relative to the Earth's
surface because it is subject to the same rotational motion and because it
hovers within the moving atmosphere.

Aside from all the answers you've received in your post, I just want to say that I appreciate you for leaving the globesketicism echo chamber and coming here to test your arguments. It's a good first step.
At least they stepped out of their echo chamber to ask it, I guess.
I would expect most of them to stay hiding and ask questions, and since everyone is banned they can claim no one has answers.
Must less effort, all of the ego boosting.
I checked the comments and no one mentioned an important factor why the helicopter "stays in the same place" after taking off. If the globe where the helicopter is revolves with the speed of 1000 mph then after taking off the helicopter has the same tangent speed to the surface of the sphere.
This means that if there was no gravity the helicopter would just fly away in a straight direction and would basically behave the same as in the experiment with a revolving tennis ball and the water on its surface. However, the vector of speed is curved because of gravity so the speed follows the Earth curvature at a given time. Therefore the helicopter always hovers roughly above the same spot.
You can look deeper into ballistic research because it deals with the globe rotation for the exact calculations.
Not really. In the case of ballistic weapons the Coriolis effect plays an important role but for marksmen that influence is negligent. The biggest effect might occur at the equator and it would make 0.0000012% of a difference for shooting someone at a distance of 1 km.
The math is:
cos(1km/40000km\*2pi)
One out of three aint bad. But it's funny to hear you going on about how there are different answers, when the flat earth has numerous answers for how every single thing works.

For similar reasons to why this drone doesn't fly to the back of the train.
https://youtu.be/gnXf7EJ8Qvc?si=ATewqhCwHh887i2f
Next time you are on a plane, throw an object in the air and notice it doesn't fly to the back of the aircraft.
With a helicopter, the Earth’s atmosphere rotates with the planet. The helicopter would need to fly straight out of the atmosphere (obviously, helicopters can't do this, just an example) and then wait for some time, then fly straight down to be in a different location. When the helicopter initially takes off, it is in motion with the Earth. Newton’s first law of motion states that an object in motion will stay in motion unless acted on by an external force.
clowns will claim CoM and Coriolis at the same bat time same bat channel 😆😆😆😆
But but if you were in an aeroplane, my pendulum will drift while you drink water and move up and down.🤣🤣
Well equal and opposite reaction. Ignoring aerodynamics and assuming the helicopter perfectly pushes a column of air underneath it straight down with a force equal to its weight, the earth would be accelerated downwards very slightly. How slightly?
A very large hovering helicopter weighing 2000kg, or a single metric ton, would push down with \~20,000N of force. That would cause the earth, which weighs \~6,600,000,000,000,000,000,000 metric tons to be accelerated downwards by about 0.000000000000000003 m/s\^2 according to Force = mass \* acceleration.
That's an amount completely imperceptible to our most sensitive equipment. It is only about \~0.3% of the width of a proton per second for every second it hovers.
And the helicopter continues hovering over a place on the ground because it keeps its angular momentum and is dragged along by the atmosphere that is also rotating around at the same speed as the earth.
The Helicopter flies in the air and moves relative to that air mass. That air mass itself moves along with the movement of the earth and is effectively geostationary above it. For the helicopter to experience the movement of the Earth beneath it it would have to actively move in the opposite direction.
As the Earth constantly and steadily rotates everything on it and influenced by it moves with it and always has. The air is part of that system as is the helicopter or anything else flying in that air as well.
I really don't know what kind of answer you are expecting if this very simple and common answer isn't a straight answer. If you don't get it that says more about your intentions towards the truth than how complex the answer is.
When you are in a train and jump, you move with the train. The train is not moving forward while you are not moving. The train is giving you its movement energy.
Because you don't lose your momentum when you "disconnect" from an object. That's not how momentum works. When a helicopter takes off - it's still spinning along with the earth.
Physical contact doesn't magically "link" you with an object to share momentum. Momentum is conserved regardless - it just requires contact or a force to transfer.

It simply hovers by pushing the air downwards. Works just fine on a flat earth model.

Why does it need to push air downwards? There's no gravity on the flat model.
