FACTBOX-Five facts about the Boeing Dreamliner

Dec 15 (Reuters) - Boeing Co (BA.N) plans to fly its new, carbon-composite 787 Dreamliner on Tuesday (see full story [ID:N10182958]).
The test flight, more than two years behind schedule, could help restore credibility for the No. 2 plane-maker behind Airbus (EAD.PA).
Here are five facts about the 787 Dreamliner:
* The 787 Dreamliner promises greater fuel efficiency through the use of durable, light-weight composite materials.
* Planes in the 787 family have list prices between $150 million and $205.5 million.
* Boeing has taken orders for 840 Dreamliners.
* The most recent delay results from a structural problem within the side-of-body joint of the aircraft -- the connection of the wing to the fuselage.
* The 787 will use 20 percent less fuel for comparable missions in similarly sized airplanes. (Reporting by Kyle Peterson; Editing by Gary Hill)
