No restricted air space
If you fly a plane around the north part of san andreas, you might go into the restricted air space. You will hear several beeps, and you will be shot at with a rocket launcher. To stop this, land and blow up the gun. It blows up just like a car. Spawn another plane and have no flying restrictions
