Boeing has completed the first 787-9 Dreamliner. The second member of the super-efficient 787 family rolled out of the Everett, Washington, factory on August 24 to the flight line, where teams are preparing it to fly later this summer.

At 20 feet (6 m) longer than the 787-8, the 787-9 will extend the 787 family in both capacity and range, carrying 40 more passengers with an additional 300 nautical miles (555 km).

With the second and third airplanes in final assembly, Boeing and the 787-9 are on track. First delivery to launch customer Air New Zealand is set for mid-2014.

The Boeing 787-9 Dreamliner is a slightly bigger version of the 787-8. Both are super-efficient airplanes with new passenger-pleasing features that bring the economics of large jet transports to the middle of the market, using 20% less fuel than any other airplanes of their size.
