What are the steps to fold an airplane?

Here's a simple way to fold a paper plane:

Step 1: Prepare a square origami with a side length of 15cm, and then fold the two opposite corners of the square paper with a side length of15cm in half.

Step 2: Fold the angle 1 in the figure 1 into an angle of 2 and align it.

Step 3: Fold the overlapping corner 3 in Figure 2 onto the corner 4.

Step 4: Turn the top corner 5 in Figure 3 on a part, and turn the back corner 6 on the same part to the back. Get figure 4.

Step 5, turn the corner 7 in Figure 4 over along the hem 8 to get Figure 5.

Step 6, turn the corner 7 in Figure 5 back along the dotted line to get Figure 6.

Step 7: Pull the corner 7 in Figure 6 apart and form a crease in the middle.

Step 8, spread the whole figure 7 around the overlapping edge 9 to obtain figure 8.

Step 9: Pinch the crease 1 1 and crease 10 in Figure 8 to get Figure 9.

Step 10: Fold the center lines 9 of the two edges in Figure 9 in half, and turn the corner 7 upward along the broken line 12 and the broken line 13 to obtain the figure 10.

Step 1 1: Fold the front corner 14 and the back corner 15 in the figure 10 along the overlapping edge 16 respectively to obtain the figure 1 1.

Step 12: unfold the upside-down front corner 14 and back corner 15 in figure1respectively by 90 degrees to form two wings of the airplane, as shown in figure 12, thus folding into a special paper airplane.
