Columbia Disaster
Space Shuttle Columbia disintegrated during re-entry, killing all seven crew

Lost on the Way Home
On February 1, 2003, Space Shuttle Columbia was 16 minutes from landing when it disintegrated over Texas and Louisiana during re-entry. All seven crew members died. Unlike the Challenger disaster, which happened in plain sight at launch, Columbia's breakup happened at 60 kilometers altitude traveling at 18 times the speed of sound. Debris fell across a 2,000-kilometer path across two US states.
A Piece of Foam
The cause was traced back to launch day, when a briefcase-sized piece of foam insulation broke off from the external fuel tank and struck Columbia's left wing at high speed. The impact damaged heat-resistant tiles protecting the wing. During re-entry, superheated plasma — around 1,500°C — penetrated the breach and tore the shuttle apart from the inside. Engineers had flagged the foam strike during the mission but were told it was not a safety concern.
The Investigation and Legacy
The Columbia Accident Investigation Board concluded that NASA's organizational culture was as responsible as the foam strike. The board found a pattern of accepting known risks as normal — the same pattern identified after Challenger. NASA suspended shuttle flights for over two years. The program eventually retired in 2011, with its duties handed off to commercial companies like SpaceX.
