The Boeing 777 first flew in 1994 and became Boeing’s 777 family of twin-engine wide-body airliners.
Boeing developed the 777 to fill a market position between existing wide-body aircraft such as the 767 and larger four-engine aircraft. Its design emphasized long range, high passenger capacity, and improved operating efficiency. The prototype made its first flight on June 12, 1994, from Boeing Field in Seattle.
United Airlines introduced the 777 into commercial service in 1995. The aircraft became notable for being the first commercial airplane designed entirely with computer-aided design methods. The 777 family later expanded into variants including the 777-200, 777-300, 777F freighter, and 777X. It is sometimes confused with the 787, but the 777 entered service earlier and uses a different airframe design and mission profile.
