Or when they created it. The first manned flight was in 1903. In less than sixty years we had this plane. That's unbelievable.

Few things about that plane that are not amazing. There is an engine on display at the aforementioned exhibit in Seattle. Every tube on the outside runs in a 'Z' configuration instead of just a straight line, because the engine grows 6 inches longer at full operational temperature.

What's more unbelievable? After 48 years we don't have anything that comes close to it and we don't even fly them anymore.
