Science Friction 04 | The Challenger Legacy: The Devil You Know
Feb 10, 2026
Miles O'Brien, CNN aerospace correspondent and longtime space reporter, shares eyewitness reporting and analysis. He recounts foam-impact tests that pierced shuttle wings. He discusses how foam caused Columbia's loss and why imaging or rescue were not viable. He reflects on cultural and engineering lessons around launch pressure and safer return-to-flight practices.

Episode notes
Foam Can Be Deadly
- Foam impacts at high speed can cause catastrophic structural damage to shuttles, contrary to earlier assumptions.
- Miles O'Brien describes tests that made clear foam traveling ~850 km/h punched manhole-sized holes in reinforced carbon-carbon panels.
Echoes Between Challenger And Columbia
- Problems from Challenger persisted into Columbia because underlying organisational causes weren't fully fixed.
- Diane Vaughan testified that without addressing systemic causes, the same failures will repeat.
Progressive Acceptance Of Risk
- Normalisation of deviance explains how small departures from safety become accepted over time.
- Adam Higginbotham and Mike Cinelli note repeated non-fatal anomalies conditioned engineers to accept greater risk.
