The shocking truth that NASA attempted to hide was that the crew of six astronauts and one schoolteacher aboard the Challenger that day had, in fact, survived the explosion and instead met their ends after they plummeted 12 miles into the ocean. Likely embarrassed by their own lack of foresight when it came to preparing the crew for what may have been a survivable loss of life, NASA withheld information and forced people to lie on their behalf in an effort to keep the general public - which had watched the explosion live on their televisions - in the dark.

My lucidity may still be intact...
