Donald Douglas discusses plane engine development

The transcript discusses the evolution of American aircraft engines, focusing on the contributions of Charlie Lawrence and George J. Maid. Lawrence's work on air-cooled engines led to significant advancements, including powering the Lindbergh flight. Maid's innovations with the Wasp and Hornet engines set new standards with built-in superchargers. The development of the turbo-supercharger, initially attempted by Ratto and later perfected by General Electric and Dr. Moss, marked a major milestone in engine technology.
