The Space Shuttle Challenger Accident Investigation

Thirty years after the space shuttle Challenger disintegrated in the clear, cold sky high above Cape Canaveral, the commander’s widow no longer feels anger at NASA and the management missteps and schedule pressure that kept the orbiters flying despite a fatal flaw in their solid-fuel boosters.

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.

On the 35th anniversary of the first space shuttle launch, the last remaining external fuel tank set sail today from its factory in New Orleans to Los Angeles and a remarkable museum attraction in the making.
