4. How far can the Dreamliner fly?The first versions can fly up to 8,500 nautical miles, which lets airlines connect cities that were once only reachable through big hub airports.

Composite Materials: Engineered materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct at the macroscopic or microscopic level within the finished structure.
Hub-and-Spoke Model: An airline network strategy where passengers travel from an origin city to a destination city through a connecting point (hub).
Raked Wingtips: Wingtip designs that are swept back and angled upwards, improving aerodynamic efficiency by reducing induced drag.
