Boeing 787 Dreamliner

The 787 Dreamliner broke new ground as the first large commercial aircraft with an airframe constructed predominantly from carbon-fiber-reinforced polymer composites. This construction reduced weight by roughly 20 percent compared to conventional aluminum, translating directly into fuel savings. The aircraft introduced larger windows with electrochromic dimming, higher cabin pressure equivalent to 6,000 feet altitude, and increased humidity for passenger comfort. Boeing pioneered a global supply chain model with major sections built by partners worldwide, though this approach caused significant delays. The Dreamliner enabled airlines to open new point-to-point long-haul routes that were uneconomical with larger widebodies.
