From Texas Standard:
Fifteen years ago today, on a clear blue Texas morning, the Space Shuttle Columbia reentered Earth's atmosphere after a successful 16-day science mission.
But after communications were not regained with Columbia when expected, it became apparent something was terribly wrong. The shuttle had disintegrated over East Texas skies, killing all seven astronauts on board.
Here are the voices of several Texans whose memories of Feb. 1, 2003 remain vivid, and whose lives were forever changed by what happened that day.
