It shouldn't come as a surprise to anyone, but on Thursday Boeing announced revised first flight and first delivery dates for its long-awaited and much-anticipated, but also troubled 787 Dreamliner. The aviation giant said it now expects the first 787 flight during the second quarter of 2009, and the delivery of the first Dreamliner in the first quarter of 2010. Prior to Thursday's announcement, Boeing had said the first flight would be in the fourth quarter of 2008.
