Video: 31 years since Challenger tragedy

Veteran CBS News correspondent Bruce Hall was not on the air when the shuttle Challenger blasted off 30 years ago Thursday. It was, after all, the 25th shuttle flight, the first of 16 planned for 1986, and news agencies were backing off expensive, remote coverage of what increasingly appeared to be a routine event.

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.

On the 30th anniversary of the Challenger disaster, crew families, friends and space workers gathered Thursday to remember the 17 men and women who lost their lives on the high frontier, 14 in two space shuttle disasters and three in an Apollo-era launch pad fire 49 years ago Wednesday.
