Reporters from ABC News investigate the tragedy of the Columbia space shuttle, which exploded on February 1, 2003, killing all seven astronauts on board. Over the course of six months, the reporters conducted their own independent investigation of the events that caused the Columbia accident. Reporters spoke with a series of safety officials, engineers, and flight director, Leroy Cain and discovered that a number of individuals tried to warn NASA about the possible problems with the vessel. As a result, ABC News released the findings two months before NASA released theirs, which managed to contain a lot of the same information. ABC News also played a large role in encouraging NASA to perform "a broad review of its safety and management practices."
