Obituary: Jack Kinzler

NASA engineer Jack Kinzler (b.1920) died on March 4. Kinzler built the full sized models of the Mercury, Gemini and Apollo spacecraft used in preflight tests and created the flags and plaques left on the Moon by Apollo astronauts. When the Skylab heatshield failed, Kinzler created a fix using fishing poles that meant the astronauts would not have to do a spacewalk.
