Now my issue is, according to scientist the earth is spinning around 1000 miles per hour. If clockwise it is impossible for the airplane to reach NZ at the speed of 480 miles/hr only. And if counter clockwise it will only take a few minutes travel. Unless the earth does not move.
Having said that the earth moves around 1000 miles per hour, that is about 17 miles per minute. So if i go up in the sky, stay there then go down after 1 minute? I should be around 17 miles away from my original spot but is that the case? the only possibility is that the earth doesn't move nor spin.
The answer is momentum.
The earth rotates at a speed of 1,000 miles per hour. When a person is standing still, he's really moving with the earth's rotation at a speed of 1,000 mph. When he jumps up, he lands at the same place because while in mid-air, he's still moving at a speed of 1,000 mph, and the ground where he lands also moved at the same speed.
When the plane is parked, it isn't really still, it just looks that way because it's also moving at a speed of 1,000 mph with the earth's rotation. Before it took off, it already had an initial momentum. The additional thrust from its engines allowed it to take off from the ground and fly.
When the plane is flying at a speed of 500 mph, its 500 mph speed is in additon to the plane's initial 1,000 mph momentum, which is the same as the 1,000 mph rotation of the earth, which is the same as the 1,000 mph movement of the atmosphere (with varying wind speeds as a result of different atmospheric pressures at different places).
Why I support flat-earth, while on the airplane I can see flat horizon. Auto-pilot mode will travel in straight direction only which they do for most long distance flight. So if the earth has curvature as globe, we would have reached higher atmosphere. But actually, it maintains the same distance from the ground. There is so much evidence of flaat earth now that the technology (like go pro) is available.
Auto pilot does not travel in a straight horizontal path.
Auto pilot travels at constant altitude. The plane has instruments that detect outside air pressure, which indicates altitude.
Setting auto pilot at a specific altitude will maintain the altitude set. Constant altitude will not cause the plane to fly in a horizontally straight path; it will cause the plane to fly in accordance with the curvature of the round earth.
Why you support flat earth? Because your mind was closed by your religious belief.
