The 787-10 has a center section that is too long to fit in the Dreamlifter.  This means that they can only be assembled at the North Charleston plant.  The conspiracy theorists amongst us may think this was a deliberate part of the plan to focus production there and close the Everett line but, whether that is true or not, Everett is now only addressing issues with airframes already built and is not building any new 787s.  However, some continue to come here from the east coast for rectification work prior to delivery.  That means we get some 787-10s showing up and one of them was for United.  I hadn’t planned on it but was there for something else and got this as a bonus.
