Here's another example of a section of aircraft returned to Boeing for use in evaluating the effects of years of regular airline service. This is a Boeing 727; originally delivered to Pan American World Airlines. Pan Am eventually sold it and it was owned by several airlines prior to decommisioning. When Boing put it on display at the Museam of Flight it was decided it should look like it did when it left the factory. Too bad this passenger wasn't allowed to disembark before all this.
