At roll rates such as this the danger of humans blacking out becomes very real. Armstrong, as the Command Pilot, kept his cool and managed to stop the roll by activating the Reaction Control System, and then orienting the Gemini craft for a perfect emergency landing into the Pacific Ocean.When I say perfect, I mean perfect. The craft came …
