Gshn28, the YouTuber and Minecraft builder who designed the contraption, used no mods or other adaptations to make this plane work. It’s all built in “vanilla” or unaltered Minecraft by incorporating command blocks, elements in Minecraft that can store and execute complicated instructions.
Players control the plane by putting special blocks in their toolbar, selecting those blocks to execute flight commands, and steering with the mouse.
The directions for building this airplane are on Mediafire, if you want to try it yourself and learn a bit how Minecraft machine engineering works in the process.
