Decompression is a space station astronaut's worst nightmare. The nightmare came true in 1997 when an out-of-control Progress cargo ship slammed into space station Mir, punching a hole in the module it struck. With alarms blaring, cosmonauts Michael Foale and Sasha Lazutkin had to use the only tool they had at hand—a kitchen knife—to saw through electrical cables linking the damaged module with the rest of the station. While this was not strictly an EVA, the cosmonauts nevertheless had to work fast to clear the hatch and close it before they found themselves in deadly vacuum—without suits. They survived, though the damaged module was never repressurized.
