The Boeing 767 is a mid-size, wide-body twinjet airliner produced by Boeing Commercial Airplanes. Passenger versions of the 767 can carry between 181 and 375 passengers, and have a range of 5200 nm to 6590 nm depending on variant and seating configuration.

The Boeing 767 is classified as a wide-body aircraft, which categorizes it as a "large" plane compared to narrow-body jets like the Boeing 737 or Airbus A320. It features two aisles in the passenger cabin and typically carries between 200 and 300 passengers, depending on the specific model (-200, -300, or -400ER) and seating configuration. While it is significantly larger than short-haul aircraft, it is considered a "medium-wide-body" when compared to "jumbo jets" like the Boeing 747 or the massive Airbus A380. The 767 was revolutionary because it was the first twin-engine wide-body to be certified for long over-ocean flights (ETOPS), allowing it to fly routes that were previously reserved for three- or four-engine planes. Its wingspan is approximately 156 feet, and it is widely used today by both major passenger airlines for trans-Atlantic routes and by cargo giants like FedEx and UPS. While newer planes like the 787 Dreamliner have largely replaced it for passenger service, its sheer size and versatility remain impressive in the aviation world.
