I think it would be a good idea to make it possible for ships to fly down into a planets atmosphere, and then fly around. On the same note, ships should be able to land on planets, either on the surface of the planet, or on landing pads on surface bases. Or even better, have both as an option.

It's a good idea to read the thread titled PLEASE READ PRIOR TO POSTING A SUGGESTION to check if your idea has been suggested before.

Which it has.

Would probably be implemented when Territorial Wars is implemented

Ahahaha, you probably played Elite dangerous: horizons and thought VO should have the same.
