Air control doesn't want airplanes changing elevations much like highway patrol doesnt want you going too fast on the highway oe changing lanes. If a plane never corrected for elevation it would go into a stall. They make planes to get to its destination safely.

Although flat earth is sooooo heavily censored, this video clearly shows the sun going around the earth - if you have eyes that see. I have hope!!
What in this video is unexpected?
If the earth were turning, and spinning around the sun, the sun would not swing back. It does though, because the sun is a small local light going around the North Pole.
