History Of Boeing 787:

In the late 1990s Boeing wanted to make a plane called the Sonic Cruiser, which would go very fast.[6] According to Boeing, the 787 consumes 20% less fuel than the similarly-sized 767.[7] But after the September 11, 2001 attacks fuel prices went up, so airlines wanted more efficient planes rather than faster ones. Boeing cancelled the Sonic Cruiser and replaced it in January 2003 with the "7E7," which was the code name for the 787 at the time. In July 2003, Boeing decided to call the new plane the "Dreamliner."

On April 26, 2004, Japanese airline All Nippon Airways became the launch customer for the 7E7, and they expected to have the plane delivered in 2008. In 2005 it was renamed the 787.[8]

The 787 was designed to be much more efficient. It did this by using composite to build most of the plane instead of aluminum, which made the plane lighter.[6] It also used two new engine types, the General Electric GEnx and the Rolls-Royce Trent 1000. According to Boeing this made the 787 20% more efficient than the 767.

In December 2006 Boeing said that the 787 was heavier than they expected, so the plane was delayed.[9] Also, Boeing had tried to shorten the time to make the plane by asking parts suppliers to assemble parts of the plane. These parts manufacturers were not used to the extra work though, and this delayed the 787 even more.

Boeing started to test the 787 on the ground. They found more problems and the plane was delayed even more. Finally on December 15, 2009 the 787 went on its first flight. Boeing began testing the plane in the air. There were more problems, like a failure of one of the Rolls-Royce Trent 1000 engines, and an in flight fire, which delayed the plane even more. Some airlines wanted to be paid back for all the delays.[10] Finally in July 2011, Boeing delivered their first 787 to ANA.
