Signage is displayed on the headquarters building of Boeing Co. in Chicago, Illinois, U.S., on Monday, April 27, 2009. Boeing Co. last week lowered its 2009 profit forecast less than analysts predicted, reaffirming the year's delivery schedule even as the recession prompts airlines to defer orders and forces the planemaker to further delay a model.
