It has been three years since I witnessed the last Space Shuttle launch, STS-135, lifting off from Earth on July 8, 2011. It was the seventh I had witnessed, but this one had special meaning. Twenty-nine years ago, I was on the inside looking out as a part of the STS-23 (STS 61-B) crew. I flew Atlantis on her second flight in 1985 and had observed her construction years earlier at Rockwell International’s space shuttle-assembly location.
