Start with a rectangular sheet of paper.
Fold the paper in half lengthwise, then unfold.
Fold the top two corners inward so they meet at the center crease.
Fold the resulting top edge down to align with the bottom edge.
Fold the paper in half along the center crease.
Fold the wings down so each side aligns with the bottom edge.
Make small adjustments to the wing tips so they match.
Fold up the trailing edge of each wing slightly for stability.
Gently crease all folds firmly.
Hold the nose level with the ground and throw forward with a steady motion.
