In the twenty-first century, airplane flight—once a remarkable feat of human ingenuity—has been relegated to the realm of the mundane. In this mesmerizing reflection on flying, Mark Vanhoenacker, a 747 pilot who left academia and a career in the business world to pursue his childhood dream of flying, helps us to reimagine what we—as pilots and as passengers—are actually doing when we enter the world between departure and discovery. In a seamless fusion of history, politics, geography, meteorology, ecology, family, and physics, Vanhoenacker vaults across geographical and cultural boundaries; above mountains, oceans, and deserts; through snow, wind, and rain, renewing a simultaneously humbling and almost superhuman activity and reawakening our capacity to be amazed.
