 Clancy Haddleburg was the very first to open the capsule and greet the astronauts. He says he was laser-focused on his tasks. His final step was the last chance where something could go wrong. The only thing I was thinking of was the next step in my checklist. Failure was not an option for NASA. Now a volunteer, Haddleburg says he relishes the chance to pass along the story to the next generation. There were thousands of us out there that day, all dedicated to one thing, making sure that the astronauts got home safe.
