The plane is not flying at am absolute speed of 600mph, but at that speed relative to the air. It is an airplane after all. And the air rotates with the earth, unless you have rejected Newton's First Law of Motion along with the rest of modern physics.
Laws of motion and modern physics is not an answer to this contradiction.
The man in the video said that the bullet does not move with the atmosphere and that the ground moves under it. The target will move away from the path of the speeding bullet if not adjusted for that movement. The Target will move into the path of a speeding bullet if the sights are adjusted properly.
You have told me that a jet does the opposite of a bullet. The jet moves with the atmosphere and the ground does not move under it. Planes do not have to adjust for a moving earth because they move with it. This is an obvious contradiction. You can't have it both ways. You can't have a bullet act one way and a jet act the opposite way.
