The 1902 glider wing had a flatter airfoil, with the camber reduced to a ratio of 1-in-24, in contrast to the previous thicker wing. The larger aspect ratio was achieved by increasing the wingspan and shortening the chord. The glider also had a new structural feature: a fixed, rear vertical rudder, which the brothers hoped would eliminate turning problems. However, the 1902 glider encountered trouble in crosswinds and steep banked turns, when it sometimes spiraled into the ground—a phenomenon the brothers called "well digging." According to Combs, "They knew that when the earlier 1901 glider banked, it would begin to slide sideways through the air, and if the side motion was left uncorrected, or took place too quickly, the glider would go into an uncontrolled pivoting motion. Now, with vertical fins added to correct this, the glider again went into a pivoting motion, but in the opposite direction, with the nose swinging downward."
