Krueger is a scientific publication presented at the Academy of Natural Sciences in San Francisco, California, during the late 19th century. The lecture delves into the historical and scientific aspects of aerial navigation, discussing the feasibility and principles of artificial flight. It aims to present an understanding of flight mechanics and advocate for further invention in this innovative field. In his lecture, Krueger provides a comprehensive exploration of the history of flight, including ancient myths and notable air voyages, while critically analyzing the design and function of existing flying machines. He argues that past attempts at achieving sustained human flight with balloons may have misled inventors, emphasizing instead the necessity of a proper understanding of aerodynamic principles. The structure of birds and other flying creatures serves as inspiration for future machines, which he believes will soon allow for practical, safe, and efficient aerial transportation. He concludes with an optimistic view of the transformative impact that successful artificial flight could have on society, commerce, and exploration.
