8. Fold the top flap down again, this time bringing up the two triangular sections. All the creases should be in the right direction for this move to occur naturally. When finished, the two triangular flaps should be tucked under the top flap.

9. Lay the play flat and press down all the creases.

10. Fold the top triangular flap on the left side over to the right. Keep the bottom edges lined up and make a vertical crease so that the tip of the triangle just touches the center line crease. Unfold when finished.

11. Position the paper so you can now work on the triangular flap just formed.

12. Fold the triangular flap over again but this time make a crease so that the left edge of the flap ends up horizontal and parallel to the bottom edge of the paper. The bottom point of this crease should hit the vertical crease made on the previous step.

13. Fold the flap back to the left to form another vertical crease. Keep the top horizontal edges of the flap lined up and make sure the tip of the flap just hits the long diagonal edge of the paper.

14. Bring the flap back to the right again forming a new crease. Make sure the left diagonal edge of the small flap lines up with the vertical right edge exactly. Press down all the flap creasese tightly.

15. Unfold all of the flap creases just made.

16. Fold the flap up so that the tip meets the point at the nose of the plane. Make sure the diagonal edges of the flap stay lined up. The lower point of the new crease should hit the center line crease exactly.

17. Unfold the flap and position and the paper to work on all the flap creases formed earlier.

18. Pick up the top layer of the triangular flap at the middle of the lower edge. As this point raises up, the left tip of the large triangular flap will move to the right and end up right at the center line crease.

19. Carefully raise the tip which is now at the center line and force it to pivot along the creases formed earlier. This difficult step can be done in two stages but all the creases needed for this complex move already exist.

20. Press everything flat and position the paper to work on the same flap on the right side.

21. Fold the top triangular flap on the right side over to the left. Keep the bottom edges lined up and make a vertical crease so that the tip of the triangle just touches the center line crease. Unfold when finished.

22. Reposition the paper so you can work on the flap just formed.

23. Fold the triangular flap over again but this time make a crease so that the right edge of the flap ends up horizontal and parallel to the bottom edge of the paper. The bottom point of this crease should hit the vertical crease made on the previous step.

24. Fold the flap back to the right to form another vertical crease. Keep the top horizontal edges of the flap lined up and make sure the tip of the flap just hits the long diagonal edge of the paper.

25. Bring the flap back to the left again forming a new crease. Make sure the right diagonal edge of the small flap lines up with the vertical left edge exactly. Press down all the flap creases tightly.

26. Unfold all the flaps and creases just made.

27. As before, fold the flap up so that the tip meets the point at the nose of the plane. Make sure the diagonal edges of the flap stay lined up. The lower point of the new crease should hit the center line crease exactly.

28. Unfold the flap and position the paper to work on the flaps and creases created earlier.

29. Pick up the top layer of the triangular flap at the middle of the lower edge. As this point raises up the right tip of the large triangular flap will move to the left and end up exactly at the center line crease.

30. Position the paper to work on the tricky part.

31. Carefully raise the tip which is now at the center line and force it to pivot along the creases formed earlier. This difficult step can be done in two stages but all the creases needed for this complex move already exist.
