How Do Gas Planets Work?

If an airplane can fly through a cloud, could a rocket ship hypothetically fly through jupiter? They don't teach these things in my public school. Well, first of all, if a plane is going fast enough, it actually can't fly through air. There comes a point at which air is dense enough, gas is dense enough that it will tear the plane apart. And that is one of the crazy things about about gases. If you're moving fast enough, they are basically a brick wall,. just like scrooge mc duck's coins.
