Happy Airships

Happy Airships is a mod that enhances long-distance travel using happy ghasts. It introduces the propeller, an item equipped via a harness that doubles a ghast's flight speed under player control. Additionally, the swiftness enchantment can be applied to propellers, boosting speed by 0.5x per level (up to 1x at level 2), for a maximum total speed multiplier of 3x.
