Are they sold? Are they for Boeing’s use exclusively forever? I’m talking about all the hours of testing for the 787 and 747-8. What becomes of these test aircraft? I understand they go through a lot of physics that normal aircraft would not be subjected to on a normal flight.
Does Boeing (or Airbus for that matter) roll a brand new unflown aircraft out of the hanger and deliver to a client or do they give them one that has been test flown for months?
