The 787, which features carbon-fiber composites that reduce weight and improve fuel efficiency, will begin test flights around early September, and delivery of the first plane to a customer is slated for May 2008. “We have no intention of being late into service,” Bair said at a news conference in Seattle on July 6. The unveiling day is symbolic: 7/8/07. Also, 60 years ago to the day, Boeing’s 377 Stratocruiser, its first plane to sell successfully to non-U.S. airlines, flew for the first time. The Stratocruiser used cutting-edge technology of the period, cabin pressure, letting it fly above the weather.
