Boeing marked a key milestone as thousands of employees gathered for the debut of the first 737 MAX 10 at the company’s Renton, Washington factory on Friday. During a ceremony, Boeing leaders highlighted the team’s accomplishments and recognized their efforts in completing production of the newest member of the 737 MAX family.

The 737 MAX 10, the largest variant of the MAX family, can seat up to 230 passengers and offers the lowest seat-mile cost of any single-aisle airplane ever produced. The airplane will now undergo system checks and engine runs prior to first flight next year.

“I’m honored to take this airplane on its first flight and show the world what you’ve put your heart and soul into,” 737 Chief Pilot Jennifer Henderson told the employee crowd.

The 737 MAX 10 currently has more than 550 orders and commitments from more than 20 customers around the globe.
