 You can see right over the door here, there's a piece of orange tape. Anybody can guess what that might be? Katie Ringgold is in charge of Boeing's 737 program and the factory in Renton, Washington, where they're assembled. She points to a piece of tape marking one single rivet on the fuselage of a plane in production that's sticking out too far from the skin of the plane. But overall, Ringgold says problems with new fuselages have dropped in recent months.
