Boeing Co successfully staged the first flight of the world's largest twin-engined jetliner on Saturday in a respite from the crisis over its smallest model, the grounded 737 MAX.
The 777X, a larger version of the 777 mini-jumbo, touched down at the historic
Boeing Field outside Seattle at 2 pm (2200 GMT) after a debut which began almost four hours earlier at Boeing's revamped wide-body assembly lines north of the city.
"It's a proud day for us," said the chief executive of Boeing's commercial airplane unit, Stan Deal.
