With Boeing Flight Test and Evaluation Captain Kirk Vining and Chief Pilot Capt. Mark Feuerstein at the controls, the airplane took off from Paine Field in Everett, Wash. at 1:30 p.m. local time and landed at Boeing Field in Seattle approximately four hours later.
"It was a great flight and the engines performed as expected," said Capt. Vining. "This is an important milestone for the flight test programme."

Boeing's efforts to improve the 747-8 family have resulted in an accumulated 1.5 percent gain in fuel efficiency since the first airplane was delivered less than two years ago.
These new improvements will give operators an airplane that is an additional 1.8 percent more efficient, according to the manufacturer.
"These improvements are a part of our commitment to continually improve our great airplanes for our customers," said Eric Lindblad, vice president and general manager of the 747 programme. "Improving fuel efficiency by another 1.8 percent saves the airlines approximately one million dollars per year in fuel per airplane and reduces the carbon footprint."
The new configuration will first deliver in early 2014 and be available for retrofit. Entry into service of the new engines and FMC software will take place in late 2013.
