Think about when you first flew. When you ascended from the ground and traveled high and fast over its turning arc. When you looked out into a new world, simply and perfectly captured through an ice-lined window. When you descended into a city from the sky as easily as a sunrise. In Air Crossing, airline pilot and romantic aviator Mark Vanhoenacker shares his unstoppable love of flying, on a journey that goes from day to night, from new forms of cartography to the poetry of physics, the names of the winds. and the nature of the clouds. The simple emotional transmission that remains at the heart of an experience that modern travelers take too much for granted: the transcendent joy of movement and the remarkable emotions that height and distance confer on everything a man can yearn for. The 21st century has relegated airplane flight — once a remarkable feat of human ingenuity — to the realm of the mundane. Vanhoenacker, who abandoned academia and a career in business to pursue his childhood dream, in a fusion of history, politics, geography, meteorology, ecology and physics, offers us a poetic exploration of the human experience of the flight that reminds us of the weight of imagination in our most ordinary journeys and rekindles our capacity for wonder across geographical and cultural borders.
