Engines
Engines give people the power to do what was once only possible in myths and dreams. Thanks to engines, you can fly halfway across the world in half a day. Astronauts can rocket up to the International Space Station in six hours. Helicopters can rescue injured people and speed through the sky to the hospital.
We live in a world filled with engines. They’re mostly out of sight, under the hoods of cars, in trucks and buses. But you can hear them, purring at red lights, rumbling down highways, revving as motorcycles race past, and roaring in planes overhead.
