After two days of weather delays, Boeing’s 777X jetliner took to the skies Jan. 25, 2020, to begin its flight test program. Based on the 777 and with technologies from the 787 Dreamliner, the 777X took off in front of thousands at Paine Field in Everett, Washington, at 10:09 a.m. local time for a 3 hour, 51 minute flight over Washington state before landing at Seattle's Boeing Field.

"The 777X flew beautifully, and today's testing was very productive," said Capt. Van Chaney, 777/777X chief pilot for Boeing Test & Evaluation.

Chaney and Boeing Chief Pilot Craig Bomben worked through a detailed test plan to exercise the airplane's systems and structures while the test team in Seattle monitored the data in real time.

Stan Deal, president and CEO of Boeing Commercial Airplanes, said, "Today's safe first flight of the 777X is a tribute to the years of hard work and dedication from our teammates, our suppliers, and our community partners in Washington state and across the globe."

The first of four dedicated 777-9 flight test airplanes, WH001 will now undergo checks before resuming testing in the coming days. The test fleet, which began ground testing in Everett last year, will endure a comprehensive series of tests and conditions on the ground and in the air during the coming months to demonstrate the safety and reliability of the design.

The newest member of Boeing's widebody family, the 777X offers lower fuel use, emissions, and operating costs through advanced aerodynamics, the latest generation carbon-fiber composite wing, and the GE Aviation GE9X jet engine.

The 777X combines the best of the passenger-preferred 777 and 787 Dreamliner cabins with several innovations. Passengers will enjoy a wide, spacious cabin, large overhead bins that close easily for convenient access to their belongings, larger windows for a view from every seat, better cabin altitude and humidity, less noise, and a smoother ride.

Boeing expects to deliver the first 777X in 2021. The program has won 340 orders and commitments from carriers around the world, including ANA, British Airways, Cathay Pacific Airways, Emirates, Etihad Airways, Lufthansa, Qatar Airways, and Singapore Airlines since its launch in 2013.
