To control saucer in the air, use a Key (Carrot on a stick).After throwing Light Blue Egg in it, you will start gaining altitude very quickly, up to the vertical end of the world.
My complaint about this and other mods about flying vehicles is controls, now I do understand that modders can't do anything about it, but Mojang must help them out with this. The look of the game will be changed in the way of a much smoother experience and better graphics. It became possible by increasing the resolution of the textures to 32x32 pixels. It can't shoot lasers or anything like that, but it looks cool and can hover on the ground. Multipixel is an alternative version of the standard texture pack but with additional details.
You cannot get into space using this alien technology, but you can climb pretty high enough for everything seems small to you. This mod adds a real flying saucer, that you will be able to ride on. UFO were spotted by the citizens of regular city in Minecraft PE, government hopes it's not an alien invasion.
