FACTBOX-Five facts about the Boeing Dreamliner

Aug 27 (Reuters) - Boeing Co (BA.N) delayed plans to deliver its first carbon-composite 787 Dreamliner until the middle of the first quarter of 2011.

The delivery to Japan's All Nippon Airways (9202.T) is already more than two years behind schedule.

Here are five facts about the Boeing 787 Dreamliner:

* The 787 Dreamliner promises greater fuel efficiency through the use of durable, lightweight composite materials.

* Planes in the 787 family have list prices between $150 million and $205.5 million.

* The 787 will use 20 percent less fuel for comparable missions in similarly sized airplanes.

* Boeing has orders for 847 Dreamliners on its books.

* The most recent delay relates to the availability of a Rolls-Royce (RR.L) engine needed for the final phases of flight testing.
