Columbia was destroyed at about 09:00 EST on February 1, 2003, while re-entering the atmosphere after a 16-day scientific mission. The Columbia Accident Investigation Board determined that a hole was punctured in the leading edge on one of Columbia's wings, which was made of a carbon composite. The hole had formed when a piece of insulating foam from the external fuel tank peeled off during the launch 16 days earlier and struck the shuttle's left wing.

As to the loss of SpaceX Starship during test flight number 3. Live video showed control instability as the left tail fin actuated during re-entry interface with the earth's upper atmosphere. Views of the right tail fin were not shown and apparently unavailable. Both left and right tail fins would need to be thermally protected and functioning properly to maintain proper attitude control. Thereby keeping the thermal tile insulated half of starship facing into the atmospheric heating. Live video seemed to show starship eventually facing sideways into the plasma field. This would expose unprotected areas of Starship to extreme heat and structural failure. Ground based imagery during ascent showed multiple pieces of falling ice impacting the left tail fin. It is probably safe to assume that similar ice strikes hit the right tail fin. Live video showed a fair amount of debris floating around during the coast phase and also seemed to show some asymmetric patterns of flames or plasma behind the Starship during re-entry. This could be visual evidence of the right tail fin burning up. Anon sees a high likelihood that these ice strikes resulted in re-entry failure of the spacecraft. Much like the loss of Space Shuttle Columbia.
