Boeing's 787 Dreamliner is scheduled to be delivered in the third quarter of 2011, more than three years behind schedule.
The first 787 has been delivered to its launch customer, the Japanese airline ANA, for final testing and Boeing claims it will represent the start of a new era of flying.
The larger windows have been made possible by the use of composite materials in the fuselage; materials that can handle the loads of larger cutouts.Boeing has also taken away physical window shades, replacing them with electromagnetic shades that allow passengers to dim the windows but still see out.
