Check — Aircraft Types

Heated air inside the balloon is less dense than the cooler air outside, which lifts the vehicle — proving controlled ascent and descent were possible and captivating the public in the early Industrial Revolution.

The Gifford dirigible added direction and propulsion: a steam engine driving a propeller allowed it to be navigated through the air — the transition from simple vertical lift to controlled, powered flight.

Fixed-wing aircraft generate lift through forward motion over the wings, making them more efficient over long distances with higher payload — helicopters excel instead at vertical take-off, landing and hover.
