10. "Wilbur and I could hardly wait for morning to come to get at something that interested us. That's happiness.“ -Wright Brothers.
11. Frustration & perseverance resulting Wright Brothers making hundreds of prototypes and testing them in a small-scale wind tunnel to measure lift and drag. Each problem solving idea they had is revealing something newand bring them closer to the idea.
12. Wright brothers hard work pays off by unlocking the secrets of control to conquer "the flying problem", rather than developing more powerful engines as some other experimenters did resulting the invention of three-axis control (X,Y,Z Axis). Pitch - Angle of X Body Axis (nose) relative to horizon. Also a positive (nose up) rotation about Y Body Axis Roll - Angle of Y Body Axis (wing) relative to horizon. Also a positive (right wing down) rotation about X Body Axis Yaw - Angle of X Body Axis (nose) relative to North. Also a positive (nose right) rotation about Z Body axis
