Challenger Revealed: An Insider's Account of How the Reagan Administration Caused the Greatest Tragedy of the Space Age (Unabridged‪)‬

The Reagan Administration pushed hard for NASA to launch shuttle mission 51L, before it was ready. 73 seconds into the launch, the shuttle exploded, killing seven people and leaving a nation traumatized. Richard Cook, the lead resource analyst at NASA for the Solid Rocket Boosters (SRBs), was the first to warn of possible catastrophic failure.

His memo, which detailed astronaut concerns and warnings from the shuttle builders at Morton Thiokol, were ignored by top NASA officials and members of the Reagan administration. In the aftermath of the explosion, NASA launched an investigation to "discover" the cause of the disaster. Though within NASA there was absolute certainty about the O-ring joint failure, they began a cover-up by publicly proclaiming that the cause of the explosion was unknown.

A Reagan administration Commission perpetrated the same lie. And when Richard Cook realized that the Commission was not interested in revealing the truth, he acted as a true patriot and hero and leaked the original O-ring warning documents to the New York Times. His article set off a cascade of disclosures about the events leading up to the disaster, including revelations by Morton Thiokol engineers that they had tried to stop the launch.
