Which Boeing wide-body twinjet first flew in 1981?

The Boeing 767 was the Boeing wide-body twinjet that first flew in 1981.

The 767 prototype completed its maiden flight on September 26, 1981. Boeing developed the aircraft alongside the narrow-body 757, sharing design features such as a two-person flight deck and common cockpit philosophy. The 767 was intended for medium- to long-range routes requiring fewer seats than the 747.

Its twin-engine layout reflected changing airline preferences and improvements in engine reliability. The aircraft became especially important on transatlantic routes after receiving extended-range twin-engine operational approvals, commonly known as ETOPS.

The 767 is sometimes mixed up with the 777 and 787. The 777 first flew in 1994, while the 787 first flew in 2009. The 757 also first flew in 1982, but it is a narrow-body aircraft rather than a wide-body jet.
