ABOUT FLIGHT SUITS
Gordon Cooper once commented: "When we were selected as astronauts in 1959, little effort was made to create a standard flying suit for us. Our classic photo in front of the F-106 jet shows how we had scrounged around to get flight equipment from the various armed services. The dark blue NASA flight suit was mainly a result of the publication of that one photograph."
