Shot 07/08/2011 # PA Video. # Astronauts Commander Chris Ferguson, Pilot Doug Hurley, Mission Specialists Sandy Magnus and Rex Walheim walk out, cheers, they wave and get on bus (silver Astrovan).  ## Thirty years after Columbia became the first shuttle to launch into orbit, Atlantis will be the last orbiter to take its final flight, ending this chapter in NASA’s storied history. During the last three decades, America has seen triumph and tragedy along the way, losing 14 astronauts in two disasters (one during takeoff - another on re-entry). This final shuttle flight is also a watershed moment for thousands of NASA staffers, as they look for what's next in manned space flight, and uncertainty with their own careers.## OUT, THEN COMING OUT OF ELEVATOR — 00000023 Astros Walk Out TRT: 1:30 07:35:27 Astros walkout and wave to crowds before getting on airstream trailer 00000022 Astros Walking TRT: 40 07:35:00 Astros walking down hallway ##
