...And what's this business about gravity anchoring a plane to its horizontal position in the air??...
Where did that come from???? I hope you didn't infer that from anything I've posted. Unless one thinks the earth will spin beneath them if they simply rise into the atmosphere. Which won't happen.
The entire atmosphere spins with the earth, and weather patterns, structures, thermal effects, etc. will alter the atmospheric conditions, forcing the pilot to account for those conditions. However, there isn't a preferred runway orientation based on the earth's rotation. As a scientist, I'm really discouraged by what I've read in this thread.

Yep. Same pattern. A few people who are completely ignorant of basic, grade school-level science insisting that their argument is valid simply because they're not smart enough to understand how dumb it is.
No, people who are simply asking a question are called names by people who themselves have no answers. Look at your own two-line post; completely ignorant, grade-school, not smart, dumb.
Now, for your brilliant explanation that the plane is attached to the center of the earth by a string and moves along with it. How is this any smarter than what the guy says in the video? It raises far too many questions than it answers.
Gravity, with a few variations in some places, is pulling uniformly downward. Without it, a plane and all the atmosphere, would fly off into space. Gravity may exert an anchoring force on a plane vertically, but not horizontally.
Another thing about the "string theory" is that if it were true, then no plane could ever go anywhere. It would permanently hover over one spot and get dragged along by the earth rotation. Now, the atmosphere moving with the earth, which makes sense, raises another question. If you are flying against the earth rotation, are you experiencing permanent headwinds up to a 1000 miles per hour then ?

I'd say the key point is are those who are simply asking a question willing to accept the answer?
I admire him for putting himself out there and speak his mind. Back on C-D, people are hiding behind silly screen names petrified they might be "doxxed." I would hire him in a heartbeat, not because he is right but because he is not afraid to think.
You would hire someone simply on the basis that they think? Everybody "thinks." The problem with these types of people is that they have just enough knowledge to be dangerous and are predisposed to conspiracy. As an employer, I wouldn't touch that with your 10' pole.

I'd say it's 50/50 that he actually believes the earth is flat. Same with most Flat Earthers.
I think they are just pointing out how much science each of us as individuals actually take on faith.
How he is wrong (also why I wouldn't hire him based on his little diatribe):
JAX to LAX is 2481 miles; he said 2000 miles - Read: he's too lazy to correctly cite the most basic and easily obtained facts.
He has completely ignored the Earth's gravity in his "analysis": The plane lands as easily on a N-S runway because everything on Earth is moving relative to the its rotation; the plane, the airport, the atmosphere, the people on the plane, the luggage -- it's all moving relative the earth. The Earth's gravity remains in effect whether you're standing on the ground or floating in the air. Gravity is a complex function of the Earth's mass and velocity in relation to that of every other celestial body within relative proximity. If the plane was the size of the moon, he might have a point. Unfortunately for him and his argument, the plane's mass is insignificant and is firmly within the grasp of the Earth's gravity.
Airplanes fly due to aerodynamic lift. Due to gravity, the atmosphere (like the plane) is generally static relative to the Earth's rotation. In order to fly, the plane must be forced through the atmosphere at a high enough velocity in order to achieve lift. However, neither the plane nor the atmosphere escapes the constant that is gravity. The plane must only obtain a differential velocity relative to the atmosphere which, like the plane, is tethered to the earth's surface by the phenomenon known as gravity.
Another thing about the "string theory" is that if it were true, then no plane could ever go anywhere. It would permanently hover over one spot and get dragged along by the earth rotation.
You do realize that the atmosphere has mass and planes have wings and engines. Right?

You are ceasing to grasp the reality that the plane is also subject to the same gravitational pull. Gravity doesn't cease to exist the moment an object leaves the Earth's surface. Planes fly because lift is obtained by moving through the air at a high rate of speed. The gravitational "string" is still a constant between the atmosphere and the plane.
Maybe we need to go back to flight school, and review the four forces of flight again. Lift, drag, thrust, and weight.
