The rocket launch sound is a bit limp and meek

[Sea_Kerman]

Real rocket launches are extremely loud, and the sound can travel for many kilometers. Perhaps it shouldn't go that far ingame, but assuming 1 tile = 1 meter, moving 20 meters away from a rocket launch shouldn't cause its sound to fade into the background. You should be able to hear a rocket launch from within anywhere in a decently-sized 60 SPM base. The sound should also last for longer, perhaps incorporating that fading crackling sound that you tend to hear as a rocket gets higher up.
