The Boeing 777 was the first commercial aircraft designed entirely with computer-aided design (CAD). This digital approach helped engineers create and test the aircraft’s structure before physical assembly.
Boeing developed the 777 during the early 1990s as a new wide-body twinjet positioned between the 767 and 747 in the company’s product range. The aircraft’s design process used three-dimensional computer models, allowing teams to identify potential interference between components and reduce costly physical mock-ups.
The 777 entered commercial service with United Airlines in 1995. It became one of the world’s most successful long-haul twin-engine airliners, with variants serving passenger and cargo markets.
The 777 is sometimes confused with the 787 Dreamliner because the 787 uses extensive composite materials and newer manufacturing techniques. However, the distinction in this fact is the fully computer-aided design process, not the aircraft’s material composition.
