If the jet in your image is supposed to be moving at 29993 m/s with respect to the Earth, then the jet diagram has absolutely no similarity to >>10766943 in which the box is moving at 7 m/s with respect to the Earth (and 29993 m/s with respect to the solar system in which the Earth moves).

Did you read the text in >>10766943? Did you read it? Read it. Did you read it yet? Read it. Read the text in that image. Actually, better yet, here's another with more text for you to read.

The whole point is that the bottom half is the frame of reference in which the Earth itself, and the Earth's atmosphere, move at 30000 m/s. What you're telling me is that you completely misunderstood this.
