The aircraft, the third Dreamliner manufactured by Boeing, flew for the first time in March 2010 and was part of Boeing's flight test program leading up to the plane's certification and entry into service.
The plane will be available for public walk-through from 12-5 p.m. on Saturday and 10 a.m.-5 p.m. on Sunday. Boeing employees, retirees and up to six guests will be allowed free admission.
The plane will be closed to visitors Nov. 10-21 while the museum prepares it for permanent exhibition.
