Boeing 777

Boeing launched the 777 program in 1990 in direct response to airline demand for a widebody sized between the 767 and the 747. Rather than design in isolation, Boeing invited eight major airlines - United, American, Delta, British Airways, Japan Airlines, All Nippon Airways, Qantas, and Cathay Pacific - into the process from day one, a collaboration known as 'Working Together' that directly shaped the aircraft's cabin cross-section, range, and payload requirements. The 777 was the first commercial airplane designed entirely using computer-aided design, with no physical mock-up built before assembly. It first flew in June 1994 and entered service with United Airlines in June 1995. It was also the first twinjet certified for extended-range twin-engine operations (ETOPS) at entry into service, opening long overwater and polar routes previously reserved for three- and four-engine aircraft. Over three decades the 777 family has become the best-selling widebody in Boeing's history, with more than 1,700 delivered and the re-engined 777X now in flight testing.

The 777 is unique in offering three distinct engine families depending on customer preference: the General Electric GE90, the Rolls-Royce Trent 800, and the Pratt & Whitney PW4000. The GE90-115B, built for the 777-300ER, holds the record as the most powerful jet engine ever certified, rated above 115,000 lbf of thrust, with the largest fan diameter of any jet engine in service.
