Drones

The first drones were hot-air balloons used in the 1800s! Later, drone airplanes took over the skies. Today, drones are used by the military, delivery companies, and even drone racers! This high-interest text explores each of these uses, as well as the history and future possibilities of drones. A diagram, timeline, graph, and pro/con comparison offer even more information about how drones work, what they’re used for, and how they may change in the future.
