 NOMEX used in Apollo 1 suit??? 

The article states: ""This version [A1C] added a white NOMEX cover layer from the G4C and G5C suits,"". The Nomex page calls it a ""flame-resistant"" material commonly used in racing and firefighting equipment, and says it was ""first marketed in 1967."" The Apollo 1 fire burned through Grissom's, White's and Chaffee's suits. Now conditions were extreme (more than one full atmosphere of pure oxygen), so it might be possible the NOMEX would burn in those conditions, but I've never seen the suits described as anything other than ""nylon"" in any of the literature. On a second reading, I see NOMEX is referred to in the Gemini suits, so you couldn't really say it was added for A1C; therefore I'm just removing it. (However, there is no citation of the NOMEX.)   "
