In Speed, Safety, and Comfort: The Origins of Delta Air Lines, former Delta Boeing 767 captain and aviation historian James John Hoogerwerf traces the evolution and growth of one of America’s most successful airlines. Delta’s story began during the early twentieth century with the fight against the cotton-devouring boll weevil, which devastated the southern economy and compelled scientists to formulate calcium arsenate powder to eradicate the invasive pest. To aid in the elimination effort, Huff Daland Company, a military aircraft manufacturer, constructed the first plane specifically designed to dispense the poison from the air. Crop dusting proved so effective, Huff Daland Dusters, the world’s first crop-dusting company, rebranded as Delta Air Service in 1928 to focus more on providing commercial services, including the transport of passengers and air mail. The following year Delta began flying its first passengers from Monroe, Louisiana, eventually establishing routes across the southeastern United States. By the eve of World War II, the firm had assumed the familiar Delta Air Lines name and boasted forward-thinking management, a modern fleet of aircraft, and increased revenue from passenger ticket sales. Now headquartered in Atlanta, Delta counts itself among the oldest and largest airlines in the world, with nearly 90,000 employees and more than 5,400 flights per day. Delta’s expansion and survival are anomalies in an industry historically dominated by government and special interests. Hoogerwerf’s masterful history of Delta’s beginnings underscores the company’s contribution to agriculture, southern industrialization, and the development of commercial aviation in the United States.

A new way forward for sustainable quality of life in cities of all sizes Strong Towns: A Bottom-Up Revolution to Build American Prosperity is a book of forward-thinking ideas that breaks with modern wisdom to present a new vision of urban development in the United States. Presenting the foundational ideas of the Strong Towns movement he co-founded, Charles Marohn explains why cities of all sizes continue to struggle to meet their basic needs, and reveals the new paradigm that can solve this longstanding problem. Inside, you’ll learn why inducing growth and development has been the conventional response to urban financial struggles—and why it just doesn’t work. New development and high-risk investing don’t generate enough wealth to support itself, and cities continue to struggle. Read this book to find out how cities large and small can focus on bottom-up investments to minimize risk and maximize their ability to strengthen the community financially and improve citizens’ quality of life. Develop in-depth knowledge of the underlying logic behind the “traditional” search for never-ending urban growth Learn practical solutions for ameliorating financial struggles through low-risk investment and a grassroots focus Gain insights and tools that can stop the vicious cycle of budget shortfalls and unexpected downturns Become a part of the Strong Towns revolution by shifting the focus away from top-down growth toward rebuilding American prosperity Strong Towns acknowledges that there is a problem with the American approach to growth and shows community leaders a new way forward. The Strong Towns response is a revolution in how we assemble the places we live.
