The Space Shuttle Challenger Accident Investigation

Boeing engineers are outfitting two decommissioned space shuttle hangars at the Kennedy Space Center for the U.S. Air Force’s secretive X-37B space plane.

It was 1986 and the U.S. Air Force was on the cusp of something unprecedented in human spaceflight — launching a space shuttle crew from California and paving the way for people to fly true polar missions.

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.
