Boeing says its second 787 will take to the skies on Tuesday.
The company has scheduled a test flight for the second jetliner at 8:45 a.m. The aircraft will take off from Paine Field in Everett, Wash., as long as flight conditions cooperate.
About 25,000 people turned out for the first test flight last Tuesday. The 787 is the first commercial airplane made mostly of lightweight composite materials.
The 787 program has been plagued by ill-fitting parts and other problems. The first flight was supposed to be in 2007, but Chicago-based Boeing Co. 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.
