This adds a new node to the game. The aviator. After crafting and placing it you will be able to fly in a radius of 50 nodes around the aviator. After 30min the aviator will disappear and you need to craft a new one. You do not have to use the 30min at once. Each time you dig your aviator the remaining time is saved. Quick call with the command /7. When you leave fly radius and keep walking, the aviator is dug automatically and returns to your inventory.
