The much-anticipated, fuel-efficient 787 Dreamliner will be unveiled today at the Boeing factory in Everett, Washington. Setbacks in production have caused 15 months of delays, and although the Dreamliner has been Boeing’s most successful and fastest selling plane in the world, late penalties and deferred revenue could give the company financial troubles.

Just last week, Middle East Airline Qatar Airways said it will seek compensation for delays on its order of Dreamliner planes, which has been delayed one year to 2011, according to Thomson Financial.

Lynn Lunsford, Aerospace editor for The Wall Street Journal told Fox Business that this is an important day for Boeing.

“Today is kind of like a report card,” he said. “they’ve got a great airplane as far as concept—as far as design, and what they’ve got to prove now is that they can build it faster than anyone’s ever built a wide-body airplane before.”

Close to 900 Dreamliners have been ordered. The largest order placed was by Quantas, an Australian airline, for 65 airplanes, followed by an order of 50 planes by All Nipon Airways out of Japan. Air Canada has also ordered 37 of the 787s, according to Reuters News.
