This mod adds a transition to supersonic speed! IMPORTANT! This mod is customized to the SuperBWarafre mod, the sound barrier in this mod can be overcome starting from ~70 blocks/second. This is done because planes in Superb warfare cannot fly faster. In the future, the mod configuration will be available. This mod can be used WITHOUT superbwarfare.
• When reaching speeds above ~70 blocks per second, the player overcomes the sonic boom.
• When switching to supersonic, dust rises from the ground below.
• New and realistic sounds of flying at high speed.
• New realistic subsonic speed sounds.
Can be compatible with SuperBWarfare and other mods that add planes.
