Boeing's second 787 flew for a little over an hour Tuesday and had a little problem along the way.
The jet took off Tuesday from Paine Field and landed one hour and six minutes later at Boeing Field.
Test pilots are reporting the main landing gear door had problems retracting.
The first test of the new 787 was last Tuesday. It's 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 Boeing was forced to push that back five times.
Boeing has orders for 840 of the jets and plans to make the first delivery to Japan's All Nippon Airways late next year.
