Video: 31 years since Challenger tragedy

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.

In the first memorial of its kind, NASA and the families of the 14 men and women who lost their lives aboard the shuttle Challenger in 1986 and Columbia in 2003 have joined together to remember the astronauts with pictures, personal mementos and, in an emotional first, iconic wreckage from both orbiters.
