Airbus' position as the world's dominant planemaker has slipped behind Boeing, and the Toulouse, France-based company is undergoing an ambitious restructuring plan that foresees thousands of job losses and sensitive factory closures. Botched management of the flagship superjumbo program dashed Airbus' hopes of dominating the market. The world's largest plane is two years late due to wiring difficulties and communication failures between Airbus plants in Germany and France. The first delivery of the 525-seat plane is scheduled for Oct. 15 to Singapore Airlines, the first of 14 customers who have ordered the A380. A sneak preview is being trailed on Airbus Web site under the headline "A380 WOW!!!," with features including a virtual tour around the cabin.
