Second 787 aircraft takes off
The jetliner, painted with All Nippon Airways colors, took off just after 9 a.m. from Paine Field and landed at Boeing Field in Seattle about 11:30 a.m.
The latest test comes one week after the 787's first flight.
The 787 program has been plagued by ill-fitting parts and other problems. The first flight was supposed to be in 2007, but Boeing was forced to push it back five times.
Boeing has orders for 840 of the jets. It plans to make the first delivery to Japan's All Nippon Airways late next year.
On Tuesday the aerospace company also announced they have purchased Alenia North America's 50 percent stake in a South Carolina fuselage subassembly plant for its 787 Dreamliner.
It makes Boeing the sole owner of Global Aeronautica LLC.
