Politically-Correct, new environmentally-friendly insulation was the true cause of the loss of the shuttle, along with the loss of seven valuable lives.

Despite the record of increased tile damage due to the switch to P.C. foam and the heightened risk of heat-shield breech, the Enviro-Nazis prevailed.

Tell everyone you know:

P.C. Foam killed the Shuttle Astronauts

NASA was granted an exemption two years ago from this freon issue.
So IF the foam did cause the Columbia to burn up on reentry I would blame it more on NASA management ( the same people who gave the OK to launch the Challenger when they were told not to because the o-rings might fail) then on PC people.
