The NASA astronaut who survived last week’s failed launch and emergency landing knew he needed to stay calm.

Air Force Col. Nick Hague, a native of Hoxie, Kan., on Tuesday described the closest call of his career: His space capsule violently ripped from his damaged rocket shortly after liftoff, then with lights flashing and alarms sounding, plunged steeply back to Earth with punishing force.
