Boeing 777, or the Triple Seven, is an amazing feat of aeronautical engineering. It is the world’s largest twin-engine jet aircraft, with typical seating capacity for 314 to 451 passengers. The range of the 777 is 5,235 to 9,380 nautical miles, and the jetliner was designed to replace older wide-body airliners such as the DC-10 and L-1011. Eight major airlines (All Nippon Airways, American Airlines, British Airways, Cathay Pacific Airways, Delta Air Lines, Japan Airlines, Qantas, and United Airlines) all had a role in developing the 777, a first in airplane design.

Ultimately, these eight airlines became known as the “Working Together” group, and they played an instrumental role in how the 777 was developed and designed. By March 1990, Boeing and the “Working Together” group had decided upon a basic design configuration with a cabin cross-section close to that of the 747 and a capacity of up to 325 passengers with flexible interiors, a glass cockpit, fly-by-wire controls, and better seat-mile costs than Airbus’s A330 and McDonnell Douglas’s MD-11.
As of 2014, the 777 was being produced in two fuselage lengths, with the 777-300 having a fuselage length 33.3 feet longer than the earlier 777-200 series. The aircraft is also delivered in freighter configuration, with the 777F entering service in February 2009.
The 777 is renowned for setting records, as it is the world’s longest-range airline and can fly more than halfway around the globe without landing for refueling. The 777 currently holds the record for the longest distance flown non-stop by a commercial aircraft. In November 2013, Boeing announced the development of upgraded 777-8X and -9X models, featuring composite wings and GE9X engines to even further extend the airliner’s range.
To accommodate airlines who might use gates made to accommodate smaller aircraft, the 777 is available with large folding wingtips, 21 feet long, but no airline purchased this option. With the design of the 777X, though, the feature has reemerged with 11-foot folding wingtips to allow 777X models to use the same airport gates and taxiways as earlier 777s.
Because of its fuel efficiency, the 777 ranks as one of Boeing’s best-selling models. Airlines have acquired the 777 as a comparatively fuel-efficient alternative to other wide-body jets, and have deployed the aircraft increasingly on long-haul transoceanic routes.
Inside the Boeing 777, passengers find curved panels, larger overhead bins, and indirect lighting. Seating options for the 777 range from six abreast in first class up to 10 across in economy class. The windows on the 777 are the largest of any current commercial airliner except the 787, measuring 15-inch by 10-inch in size.
During its career, the 777 has only been involved in 10 aviation accidents and incidents, including three confirmed hull-loss accidents and three hijackings. In the most recent incident, Malaysia Airlines Flight 370, a 777-200ER carrying 227 passengers and 12 crew, was reported missing during its flight from Kuala Lumpur to Beijing. The aircraft disappeared from Air Traffic Control in Vietnamese air space over the South China Sea.
