13. Apollo 1

Apollo 1 was going to be the first test mission for the manned moon flight. NASA was testing it at Cape Kennedy (IIRC). The capsule used a pure oxygen environment. A loose wire sparked, and the oxygen in the capsule fed the flames as the three people in the capsule were burned to death. After that, NASA stopped using pure oxygen environments, and spent a few years revamping the space program.

Wonderful -but destructive - stuff, oxygen.
