NEW YORK (AP) — Boeing said final assembly of its 787-10 plane, a planned larger version of its “Dreamliner” aircraft, will take place in South Carolina.

The company says the work will be done in North Charleston, South Carolina, because the plane is too large to efficiently transport it from North Charleston to a facility in Washington state. The 787-10 is still being designed and Boeing expects to start final assembly of the first planes in 2017.
