Development

During the late 1990s, Boeing considered replacement aircraft programs as sales of the 767 and 747-400 slowed. Two new aircraft were proposed. The 747X would have lengthened the 747-400 and improved efficiency, and the Sonic Cruiser would have achieved 15% higher speeds (approximately Mach 0.98) while burning fuel at the same rate as the 767.[4] Market interest for the 747X was tepid; however, several major American airlines, including Continental Airlines, showed initial enthusiasm for the Sonic Cruiser, although concerns about the operating cost were also expressed. The global airline market was disrupted by the September 11, 2001, attacks and increased petroleum prices, making airlines more interested in efficiency than speed. The worst-affected airlines, those in the United States, had been considered the most likely customers of the Sonic Cruiser; thus the Sonic Cruiser was officially cancelled on December 20, 2002. On January 29, 2003 Boeing announced an alternative product, the 7E7, using Sonic Cruiser technology in a more conventional configuration.] The emphasis on a smaller midsize twinjet rather than a large 747-size aircraft represented a shift from hub-and-spoke theory toward the point-to-point theory, in response to analysis of focus groups.

 

Randy Baseler, Boeing Commercial Airplanes VP Marketing stated that airport congestion comes from a large numbers of regional jets and small single-aisles, flying to destinations where a 550-seat A380 would be too large; to reduce the number of departures, smaller airplanes can increase 20% in size and airline hubs can be avoided with point-to-point transit.

The replacement for the Sonic Cruiser project was named "7E7"(with a development code name of "Y2"). Technology from the Sonic Cruiser and 7E7 was to be used as part of Boeing's project to replace its entire airliner product line, an endeavor called the Yellowstone Project (of which the 7E7 became the first stage).[ Early concept images of the 7E7 included rakish cockpit windows, a dropped nose and a distinctive "shark-fin" tail. The "E" was said to stand for various things, such as "efficiency" or "environmentally friendly"; however, in the end, Boeing said that it merely stood for "Eight".In July 2003, a public naming competition was held for the 7E7, for which out of 500,000 votes cast online the winning title was Dreamliner. Other names included eLiner, Global Cruiser, and Stratoclimber.

The shortest Dreamliner variant, the 787-8 was the first variant to fly in December 2009, then the longer 787-9 in September 2013, to be followed by the longest variant, the 787-10. They are called B788, B789 and B78X in the List of ICAO aircraft type designators. The short-range 787-3 was cancelled in 2010.
