A fully deployed OTIS, with the secondary mirror extended over the primary mirror, is removed from Chamber A after a successful thermal-vacuum test in 2017. Seen still in the chamber is a sunshield simulator, called the L5 Simulator, representing the fifth and innermost layer of the sunshield. The telescope would be shipped to the Northrop Grumman facility in California to be integrated with the real sunshield. I was suspended on a lift for this shot. Page 119
