The parachute mod for Minecraft comes with the galactacraft mod. The galactacraft mod is a space shuttle which allows players to go into space. When leaving the galactacraft mod, a player will use the parachute mod to land safely on the ground. While players could still travel to space without it, the parachute mod is still important to Minecraft.
Without this mod, players would not be able to safely jump from high places without the use of potions and/or cheats. This mod has changed the game because it allows a safe landing without losing health.
