Inside The World’s Largest Twinjet Freighter As Boeing Starts 777-8F Wing Assembly

Boeing has begun wing assembly on the company’s hallmark Boeing 777-8F Freighter, the world’s most capable twin-engine cargo aircraft. This marked a tangible build milestone for the dynamic Boeing 777X freighter program. The company’s first wing spars, each of which was over 100 feet, have now been put together alongside the corresponding skin panels at Boeing’s Composite Wing Center in Everett, Washington. Major assemblies are also progressing at the Japanese program partner, Mitsubishi Heavy Industries.
