Boeing Launches SE7 Dreamliner: Fuel Efficiency for Smaller Carriers

The Dreamliner, a passenger jet, is designed to bring the economics of large jets to smaller carriers. The SE7 model is built to use 20% less fuel than similar-sized planes, addressing fuel as a major cost for airlines. This efficiency is achieved by using lightweight graphite-based composite materials instead of traditional aluminum, maintaining strength while reducing weight.
