The Boeing 767 is a mid- to large-size, mid- to long-range, wide-body twin-engine jet airliner built by Boeing Commercial Airplanes. It was Boeing's first wide-body twinjet and its first airliner with a two-crew glass cockpit. The aircraft has two turbofan engines, a conventional tail, and, for reduced aerodynamic drag, a supercritical wing design. Designed as a smaller wide-body airliner than earlier aircraft such as the 747, the 767 has a seating capacity for 181 to 375 people, and a design range of 3,850 to 6,385 nautical miles, depending on variant. Development of the 767 occurred in tandem with a narrow-body twinjet, the 757, resulting in shared design features which allow pilots to obtain a common type rating to operate both aircraft.
