The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet.[4][5] The 777 was designed to bridge the gap between Boeing's other wide body airplanes, the twin-engined 767 and quad-engined 747, and to replace older DC-10s and L-1011 trijets. 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.
