A Boeing 787 Dreamliner flies over Farnborough airport, before landing ahead of the Farnborough International Airshow, Farnborough, England, Sunday, July 18, 2010. Deliveries of the long-range passenger jet to the first Japanese customer have been delayed by more than two years due to production problems. Boeing executives have said they aim to deliver the first Dreamliner to Japan's All Nippon Airways by the end of 2010, but they have cautioned that the delivery could be delayed to early 2011.
