Hodgkins’s entry in the Let’s-Read-and-Find-Out Science series draws a visual timeline from centuries back, when humans’ dreams of flying evolved into reality. The succinct, simplified text cites human efforts to fly like birds and describes the aeronautical physics of gliding using drag force, thrust and lift. Kelley’s breezy illustrations convey a buoyant tone and keep the explanations understandable for curious young minds. Two pages of backmatter provide “Flying Facts” and instructions for making a paper airplane. Lightly touching on everything from the days of imagining the winged Icarus and dreaming of wings to today’s nonchalance about air travel, this is a welcome addition to easy science books about humans and flight.
