"The 787-9 that made its first flight on Tuesday from Boeing's Everett, Wash., factory looks a lot like the 787-8, the version that has been flying passengers since late 2011. The 'Dash Nine,' as the new plane is known within Boeing, is 20 feet longer than its predecessor, can fly a few hundred miles further without additional fuel, and—with a capacity of 270 to 290 seats—can hold about 40 more passengers.
"Boeing engineers designed only 40% of the parts for the original Dreamliner [787-8] * * * For the Dash Nine, Boeing reversed course, designing 60% to 70% of plane internally, Mr [Scott] Fancher[, Boeing's vice president of airplane development,] said. That's comparable with its previous all-new jet, the long-range 777, which was first delivered in 1995. Boeing also has started manufacturing more of the plane itself作者: choi 时间: 9-18-2013 15:38

"The single-aisle CSeries makes Bombardier the first new entrant in the market for the smallest category of mainline passenger jets since 1987, when Airbus, now a unit of European Aeronautic Defence & Space Co, first flew its A320.
"The CSeries could be the last all-new aircraft from a Western manufacturer to enter the market for some time. Companies in Japan, China and Russia are all working on new jets. But while Airbus, Boeing and Embraer SA—a Brazilian manufacturer that like Bombardier has focused on smaller, regional jets—all plan major modifications to existing models, they aren't known to be working on all-new designs now
Bombardier "claims [CSeries] is 20% better fuel efficiency than competing models * * * Monday's takeoff was nearly silent
"The CSeries program is running roughly nine months behind schedule—the first flight was originally scheduled for last December—but that pales in comparison with the delays and cost overruns suffered by Boeing and Airbus in developing their newest jets.
"Bombardier expects the development to cost $3.9 billion, said Mike Arcamone, president of Bombardier Commercial Aircraft, a unit of the aerospace division. The company had previously estimated the cost at $3.4 billion.
"Bombardier has said it plans to deliver the first CSeries after it completes certification by regulators, which itself could take a year following Monday's flight.
Note:
(a) Quotation 1 neglects to mention Sukhoi Superjet 100 http://en.wikipedia.org/wiki/Sukhoi_Superjet
("Its maiden flight was conducted on May 19, 2008. On April 21, 2011, the Superjet 100 undertook its first commercial passenger flight, on the Armavia route from Yerevan to Moscow")
(b) For quotation 2, take notice of emphasis on "Western" and that Japan, China, and Russia all working on NEW jets.
