A flight on solar wings

A lifetime devoted to flight and innovation reveals both the wonders and the warnings of human progress. One vivid fact: today, humans, pets, and livestock make up 98 percent of all land and air vertebrate mass, leaving wild nature a tiny fraction. From record-breaking human-powered airplanes to solar-powered drones, each leap forward sparks reflection on our dominance over nature. In the age of technological power, the question of how to balance invention with stewardship grows ever more urgent.
