Man Who Predicted Space Shuttle Challenger Disaster Dies

SALT LAKE CITY (AP) — Bob Ebeling had spent three decades filled with guilt over not stopping the explosion of the space shuttle Challenger, but found relief in the weeks before his death.

Ebeling's daughter Leslie Serna says her father died Monday at the age of 89 in Brigham City, Utah. She says her father was finally able to forgive himself. NPR reports Ebeling had been a booster rocket engineer at a NASA contractor during the 1986 launch.

He tried to convince them to postpone it, saying the cold temperatures could cause the shuttle to explode. Hundreds of people called and sent Ebeling supportive letters following a January NPR story about the 30th anniversary of the Challenger disaster, trying to ease his guilt.
