When Boeing unveiled the 787 Dreamliner in 2007, it promised nothing less than a revolution in air travel. With its lightweight composite fuselage, unprecedented fuel efficiency, and passenger-focused design, the Dreamliner was heralded as the future of long-haul aviation. Airlines lined up with record-breaking orders, eager to harness the possibilities of a jet that could open new routes, reduce costs, and redefine comfort. Yet behind the celebratory rollout was a story of immense complexity and challenge. Globalized supply chains, ambitious new technologies, and relentless schedule pressures led to repeated delays, production struggles, and costly setbacks. The worldwide grounding of the fleet in 2013, following lithium-ion battery fires, marked one of the most dramatic crises in modern aviation. Still, the 787 endured. With variants spanning the 787-8, 787-9, and 787-10, the Dreamliner grew into a workhorse of international airlines, reshaping route networks and helping carriers weather the turbulence of the 2010s and 2020s. From its role in pioneering point-to-point long-haul travel to its place in a post-COVID aviation industry, the 787 is both a technical triumph and a cautionary tale about the risks of innovation. Dreamliner: Boeing's Bold Gamble and Its Turbulent Triumph is a comprehensive narrative of one of the most significant aircraft of the twenty-first century-an airliner that reflects not only Boeing's ambitions, but also the evolving story of aviation itself.
