Boeing’s 777X Completes More Than 4,000 Flight Hours as Jet Approaches Final Certification

OKLAHOMA CITY – The Oklahoma Space Industry Development Authority (OSIDA) Space Port was the site of crucial brake testing for Boeing’s 777X test aircraft in March 2025. The spaceport also hosted the jet in April 2025 for additional performance evaluations.

The Boeing 777X is slated to be the world’s largest and most efficient twin-engine jet. The new jet will focus on improving passenger experience during long-haul flights with bigger windows and a wider cabin. The 777X features fuel efficiency with a greater range, lower Co2 emissions and lower operating costs. The design includes folding wingtips, new GE9X engines, and advanced aerodynamics.

OSIDA continues to be a valuable location for major aerospace companies for flight testing and research. The spaceport boasts one of the largest runways in North America as well as 96 acres of concrete apron for aircraft parking, storage, ground testing, and assembly. With a focus on robust safety and security measures as well as a full-service premier Fixed-Based Operator (FBO) to offer Jet-A fuel and aircraft repairs, OSIDA is ideal for both private industry and military use.
