Dayshot: Held together by slime blocks and redstone, the Minecraft X-Wing blazes through the trench, heading towards the Death Star’s thermal exhaust port. This is the video the GIF is from:
As you can see, in real-time, the X-Wing actually moves a lot more slowly.

The video showcases a Command Block-based X-Wing made by MythicalSnowman, on Adrian Brightmoore’s Death Star map. Cubehamster, who put the clip together and submitted the trench run webm to Reddit, noted in a comment that the footage was sped up 32x to create the effect.
If you want to have a look at it yourself, you can find instructions to summon the X-Wing in your Minecraft world here.
Dayshot showcases some of the prettiest, funniest game-related screenshots and art that we can find.
Looks more like a Rorschach ink blot than an X-wing.
