Engineering film footage of the final shuttle launch

A five-week, 5,000-mile sea trek of the last space shuttle external fuel tank pulled into port today for a parade through the urban jungle of Southern California on Saturday to its final destination.

Former Johnson Space Center Director Christopher Columbus Kraft Jr., the man who created the iconic role of NASA flight director during the Mercury and Gemini programs and whose no-nonsense, uncompromising management style defined control room operations and discipline through the Apollo years and beyond, died Monday. He was 95.
