On Saturday afternoon, Boeing rolled out the first 787 Dreamliner, set to be delivered to All Nippon Airways (ANA) in Japan, for its long-awaited debut.

The 787 Dreamliner is a lightweight airplane that promises 20 percent greater fuel efficiency than similarly sized planes. Made mostly of carbon composites or super durable plastic, the plane is a much more environmentally-friendly and cost effective option for airlines. Boeing is expected to apply the technology to future planes.

The interior includes 264 seats (12 business and 252 economy) with personal television sets, roomier seats, more storage space, an arched entry way with beverage bar, dimmable windows, and larger lavatories.

Boeing showed off the new plane to ANA executives and crew at its Everett factory north of Seattle.

At a price tag of roughly $200 million per plane, Boeing claims more than 800 orders for the 787.

The company is the world's second-largest plane-maker after Airbus.

Three years overdue and billions of dollars over the budget, Boeing's outsourcing of much of the plane's construction to foreign contractors is said to be at blame for the delays and cost overruns. They will deliver the 787 Dreamliner to ANA next month in Tokyo.

Here's a look at the 787 Dreamliner's sunny debut in Seattle:
