4. The Silence of Roger Boisjoly
Roger Boisjoly, an engineer at Morton Thiokol, repeatedly warned about the Challenger’s O-ring vulnerability in cold temperatures. His urgent concerns were dismissed, and after the disaster, he became a symbol of the cost of speaking up—facing isolation and professional backlash. Boisjoly’s experience mirrors the fates of many whistleblowers: ignored when it matters most and sidelined when vindicated. His story remains a powerful cautionary tale about the risks—and importance—of challenging unsafe decisions.
