Before the days of astronauts, there were missileers. I guess it was before the days of rockets, too. This photo is from a 1959 Observer.
This missileer is dressed for a date with the moon. His Enjay Butyl rubber suit is impervious to liquid oxygen, hydrogen peroxide, fuming nitric acid and other chemical rocket fuels. The suit is made of a combination of cotton-fabric base and resin-modified butyl. This newest of Space Age fashions was developed buy the Army Quartermaster Research and Engineering Command to protect missile-servicing crews on launching pads.
