About 100 teammates at the 777X Composite Spar Shop in Everett, Wash., cheered Monday as Casey McDowell operated the controls to drill the first hole into a wing spar for the 777-8 Freighter.

  • With that step – Boeing's traditional start of major assembly – the 777/777X team has started production on the 777-8 Freighter. The airplane is designed to be the world’s largest and most efficient twin-engine freighter, program leaders said.  
  • “You don’t forget these moments,” McDowell said. “Having our team together as we got underway on this airplane was special.”

Airlines and cargo operators have ordered 59 777-8 Freighters since Boeing launched the program in 2022. Boeing has said it is working to deliver the first 777-8 Freighter in 2028.

Meaningful moment: For Robin Thorning, an automation manager with 38 years at Boeing, this milestone was particularly poignant. 

  • “I helped build the very first 777 – WA001 – early in my career, and it’s exciting to get to start our newest member of the 777X family,” said Thorning.
  • Thorning and his father, son and daughter also share nearly 100 years of Boeing service. 
  • “To touch these incredible airplanes and help bring them to life is a privilege and really a once-in-a-lifetime opportunity. We take our work seriously as we continue to drive to build safe and more-efficient airplanes,” Thorning said. 

Catch up quick: Teams at the nearby Composite Wing Center fabricated the spars, along with skin panels and stringers.

  • Each wing has two spars – front and rear – that measure 108 feet (33 meters) long. 
  • Fabricating a pair of spars for each wing requires 392 miles of carbon fiber tape – the length of the drive from Everett to the state of Montana.
  • The combined weight of a pair of spars is 2,500 pounds.

What’s next: Teams will move the finished spars to the main factory, where they’ll be assembled into the first 777-8 Freighter wings with the CWC parts and other components. 

  • “You are leading the way as we introduce our newest freighter into our production system,” said Jason Clark, 777/777X vice president and general manager. “Thank you for building our future.”

About the family: The 777-8 Freighter is one of three members of the 777X family, which also includes the 777-9 and 777-8 passenger airplanes. The three are the newest members of Boeing’s market-leading widebody family.
