The Boeing 777 is a family of long range wide body twin engine airliners built by Boeing Commercial Airplanes. It carries between 305 and 550 passengers and has a range from 5,600 to 8,870 nautical miles (10,400 to 16,400 km). The first flight of the 777 was on June 12 1994. Distinguishing features of the 777 include the set of six wheels on each main landing gear, its perfectly circular fuselage cross section, and the blade-like rear tail cone. The Boeing 777 was first introduced on June 7 1995 with United Airlines.

The 777-200 (772A) was the initial A-market model. The first customer delivery was to United Airlines (FAA: N777UA) in May 1995. It is available with a maximum take-off weight (MTOW) from 505,000 to 545,000 pounds (229 to 247 tones) and range capability between 3,780 and 5,235 nautical miles (7,000 to 9,695 km).

The 777 was the first commercial aircraft to be designed 100% by computer. No paper drawings were ever produced; everything was created on a 3D CAD software system known as CATIA. This allowed a virtual 777 to be assembled in cyberspace, allowing engineers to examine for interferences, and to test if the many thousands of parts would fit together properly before costly physical prototypes were manufactured.

The Boeing 777 currently is available in six models: 777-200, 777-200ER (extended range), 777 200LR (longer-range), 777-300 and the 777-300ER, and the 777 Freighter.
