NASA is releasing a video of the last recorded minutes of space shuttle Columbia's crew.
The tape ends four minutes before the first sign of trouble on the shuttle as it descended toward its fiery end on Feb. 1.
Searchers found the digital tape in east Texas early this month.
Officials said the tape offers no important new information for the investigation. The 13-minute recording shows four crew members going through routine tasks in the cockpit.
NASA acknowledged having the tape earlier this week. Officials said they wanted family members of the seven astronauts to see the tape before it was released.
