Even Leonardo Da Vinci wrote many studies on the motion and velocity of paper airplanes. A system of symbols and signs to represent folds has been initiated to better universalize origami patterns. I will try using words to describe the folds. Select a square piece of suitable paper. Crease mountian folds along both diagonals.
Valley fold lengthwise in both directions.
From one mountian fold, collapse sides into center, creating a triangle base. Rotate 180 degrees. Valley fold down both front flaps to the center line. Flip the model over. Crease in half.
