Our visit to the Boeing Factory Tour at Everett with our visitors not only included the escapees from the hurricane that I covered here but also included the ongoing production test flying activities.  The 767 line is only producing freighters and tankers these days and the majority of the freighters have been going to FedEx.  This one undertook a test flight while we were there.  We saw it head out and, when it returned, it flew a missed approach before landing.
