Only days before the much anticipated first test flight of the long-awaited Boeing 787 Dreamliner, Boeing has had to embarrassingly announce yet another delay – the fifth so far – to the aircraft’s delivery schedule due to a newly discovered technical problem. Chicago-based Boeing said this week that it needs to reinforce small areas near where the wings connect to the fuselage before conducting the first test flight, which Boeing had insisted would occur before July. A revised schedule for the flight, as well as first deliveries to customers, will not be announced for several weeks. Customers had expected to get the first of the new jets in the first quarter of 2010 , nearly two years behind schedule with Japan’s All Nippon Airways slated to receive the first of the new planes. The 787 is Boeing’s first new aircraft since the 777, which was introduced more than a decade ago. Airlines around the world have ordered the 787 in record numbers, and Boeing currently has orders for 866 of the planes from at least 56 customers. Some 58 orders have been canceled this year and the delays have cost Boeing both credibility and billions of dollars in anticipated expenses and penalties.
