I met Senator Ernest F. “Fritz” Hollings (D-SC) in 1985 in the aftermath of the Space Shuttle Challenger disaster. I had testified before the Rogers Commission after I leaked documents to the New York Times about NASA’s past knowledge of flaws with the O-ring joints whose failure caused Challenger to blow up. Later I told commission investigators and the press it was political pressure from the Reagan White House that likely caused NASA to overrule the engineers who tried to stop the launch.
Senator Hollings, then senior Democratic member of the Republican-controlled Senate Commerce Committee, thought the same thing. He wanted the Senate to conduct its own investigation, but the Republicans blocked it.
