The Boeing 777, commonly referred to as the Triple Seven, is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. It is the world’s largest twinjet. The 777 was designed to bridge the gap between Boeing’s 767 and 747, and to replace older DC-10s and L-1011s. Developed in consultation with eight major airlines, with a first meeting in January 1990, the program was launched on October 14, 1990 with an order from United Airlines. The prototype was rolled out on April 9, 1994, and first flew on June 12, 1994. The 777 entered service with the launch customer, United Airlines, on June 7, 1995. Longer range variants were launched on February 29, 2000 and were first delivered on April 29, 2004
In the early 1970s, the Boeing 747, McDonnell Douglas DC-10, and the Lockheed L-1011 TriStar became the first generation of wide-body passenger airliners to enter service. In 1978, Boeing unveiled three new models: the twin-engine Boeing 757 to replace its 727, the twin-engine 767 to challenge the Airbus A300, and a trijet 777 concept to compete with the DC-10 and L-1011. The mid-size 757 and 767 launched to market success, due in part to 1980s’ extended-range twin-engine operational performance standards (ETOPS) regulations governing transoceanic twinjet operations. These regulations allowed twin-engine airliners to make ocean crossings at up to three hours’ distance from emergency diversionary airports. Under ETOPS rules, airlines began operating the 767 on long-distance overseas routes that did not require the capacity of larger airliners.

Boeing delivered the first 777 to United Airlines on May 15, 1995. The FAA awarded 180-minute ETOPS clearance (“ETOPS-180“) for the Pratt & Whitney PW4084-engined aircraft on May 30, 1995, making it the first airliner to carry an ETOPS-180 rating at its entry into service. The first commercial flight took place on June 7, 1995, from London Heathrow Airport to Dulles International Airport near Washington, D.C. Longer ETOPS clearance of 207 minutes was approved in October 1996
