Unfortunately, his "Ornithopter" didn't work, and indeed, the airplanes of today do not have flapping wings! We also tried it with balloons. Huge 245-metre long airships that needed the guts of between 80,000 to 200,000 cows! But, it was the kite that became the forerunner of the flying machine. A kite made by the now famous Wright brothers. The two brothers were bicycle repairmen, which convinced them that a flying machine could be highly unstable and yet controllable, such as with bicycles. They built their kites as strong as their bicycle frames and used bicycle parts to test their workings. The early Wright planes could manage no more than 65 km/h. Nowadays, a commercial plane can top 800 km/h. What is it that make our current planes fly 12 times faster? Well, one British Royal Air pilot, Frank Whittle,...
