Hey there!
When Columbia re-entered the Earth, the hot gases in the atmosphere (atmospheric gases), they destroyed the wings and it ultimately was destroyed. That technically means that the spacecraft wasn't shielded correctly, and led to a tragedy as well as major rethinking and reform for NASA.

Hope this helps!
