Boeing has released the first video of Boeing 777X inflight on its test flight over Washington State. The stunning video was shot from the T-38 chase plane. The 777X, lifted-off for the first time at Paine Field, Everett, Washington at 10.09 am local time on Saturday for an almost four hour flight. In a massive morale boost for Boeing, the 777X lifted off effortlessly to the cheers of thousands of Boeing employees and the public. The video below covers the take-off, air-to-air and landing and is what is called B-Roll with no sound for use by media for background shots with a voice-over. The air-to-air segment is at the 3.37-minute mark. https://www.youtube.com/watch?v=XNZ6EJ3_0Yg Here is an image from Flightradar 24 of the actual route: And here is the speed and altitude profile. Note the constant change of speed (yellow line) as the pilots test the 777X's handling characteristics. In command were Boeing chief test pilots Capt. Van Chaney and Capt. Craig Bomben. "The 777X flew beautifully, and today's testing was very productive," said Capt. Van Chaney, 777/777X chief pilot for Boeing Test & Evaluation. "Thank you to all the teams who made today possible. I can't wait to go fly your airplane again." SEE our superb photo galleries. Capt. 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. "Our Boeing team has taken the most successful twin-aisle jet of all time and made it even more efficient, more capable and more comfortable for all," said Stan Deal, president and CEO of Boeing Commercial Airplanes. "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 over the coming months to demonstrate the safety and reliability of the design.
