I would also point to heavier-than-air flight. For thousands of years people tried to mimic flapping wings of birds, but in the end it was the unnatural propellor and fixed wing design that gave us flight.
- serf 9y agoFixed-wing flight isn't unknown to the natural world.[0] Flagella use propeller motion for propulsion.[1] Lots of animals use jets.[2] I'd consider the combustion engine to be the most novel 'human' design with regards to aircraft propulsion -- or the way we achieve jet propulsion; that's pretty unique.
