Boeing offers a glimpse of the world's largest two-jet aircraft

Dubai, United Arab Emirates (CNN) - Boeing recently unveiled its new 777 X-9, the first 777 first-generation aircraft. After the "fully assembled" test plane was taken from the Boeing plant in Everett, Washington, at the beginning of September. Although the plane will never fly in the sky, it will undergo a year of tests on the ground to investigate its structural strength and precision in design. Although the structure of the aircraft has become substantially complete, it still lacks certain components, such as engines and avionics systems. "The static test is our chance to confirm the design of the airframe structure and components," says Dorina Bingo, director of the 777X test and evaluation program. When completed, the wing will extend 235 feet and 5 inches, the longest in the company's 99-year history. The wing of the wing of the plane is only 12 feet long and is anchored with pins to be installed to prevent it collapsing while flying. The wings are further enhanced by the airline's airliner, helping fuel up to 12% more than the Airbus A350, according to Boeing. It was tested with a payload of more than one and a half times the weight, resulting in the wings being twisted more than 26 feet. The aircraft can accommodate between 350 and 425 passengers. It is scheduled to be operational in 2020, with pilot flights starting next year. Boeing said the cost of operating the new aircraft would be 10 percent lower than the A350-100. The aircraft is expected to reach more than 14,000 kilometers, equivalent to the distance between Dubai and Panama City. Many airlines have already applied for the new Boeing, including Emirates, Al Nippon Air Lines and Lufthansa. The new Boeing X family comes as part of an engineering revolution that allows two-engine jetliners to take the same global routes for the larger four-engine, fuel-efficient aircraft, such as the 747 and the A380 Super Jumbo.
