Boeing Sees ‘No Mystery’ as Finished 787 Dreamliners Redone

Boeing Co. promised to deliver the first 787 Dreamliner by September as planned after three years of delays and to ship as many as 20 in 2011 as mechanics rework finished planes to meet new specifications.

Dreamliners will need to be modified through next year in the “factory within a factory” set up in Everett, Washington, where Chicago-based Boeing builds all its wide-body jets, Chief Executive Officer Jim McNerney said today on a conference call.
