if a rocket goes off the globe so can a plane
The entire world is sorrounded by antartica whats beyond antartica is protected or you arent allowed
A globe is a model of the earth. I gave you the link. A rocket cannot go off the globe nor can a plane.
A rocket must be powerful enough to leave the earth's atmosphere. Here are the layers

Due to pressure and other issues, planes have a certain ceiling that they can go to. And the Space Shuttle as well. That diagram in the link shows you.
The world is not surrounded by antarctica. How is that even possible? in order to be surrounded by a an continent that is covered in ice, that would affect our climates, and all the continents wouldn't be what they are today.
If you are familiar with the continental drift, you know that the continents used to be all together as a super continent called Pangea. This supercontinent contained all the continents and was surrounded by a super ocean called Panthalassa.
Pangaea or Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It formed approximately 300 million years ago and began to break apart after about 100 million years. Wikipedia
https://en.m.wikipedia.org/wiki/Pangaea You can see how the continents fit together like a puzzle. South Americs fits up to Africa, etc.
And you say beyond Antarctica is protected? Why?
Explain circumnavigation---which is going around the earth
Circumnavigation (literally, "navigation of a circumference") refers to travelling all the way around an island, a continent, or (usually) the entire planet Earth.
People travel all over the world every day. Some have travel around the world. They make it a contest. So, if the world was really flat, then why are there contests? I suggest you travel. And you will see that what you are saying is incorrect.
