I didn’t know this, but Yes, there is! It’s a nod to NASA flight director Gene Kranz and his stylish vests. When NASA established mission control, they broke the shifts up into three teams, red, blue and white. Kranz was on the white junior team. Well, he was a fan on the 3-piece suit (who isn’t?) and his wife liked to sew and Viola: a tradition was born. He would wear a specially-made white vest for each mission and during splash down would wear a festive version such as gold and silver or a sequined red, white, and blue. You can see some reference to this in the movie, Apollo 13. Kind of an adorable story, and I love that Ray would have it as his crisis wear!
