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.

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,...
