Summarize this article in one sentence.
Take one of the edges of the triangle that’s on top of the spaceship and fold it so it lines up with the point. Crease the paper slightly so it comes up at a slight angle. Fold the other side of the top triangle so the center edges are aligned. These folds will look like windows on your spaceship’s cockpit. Locate the 2 wings on the back of the ship. Grab the end of the wing and fold it back about 1⁄2 in (1.3 cm). Make sure the back edge stays lined up so the folds form triangles. Repeat the process on the other side to add points to your wings and make your spaceship look faster. You can also keep the wings straight if you want. Slightly bend the edge on the back of the ship up so it looks like tailfins. You can also hold onto the back edge of the ship to play with it and pretend that it’s flying.

Summary:
Fold the edges of the top-most piece to make the windows of your spaceship. Bend the tips of the wings up. Crease the back of the ship to create a spoiler.
