I have wondered how vulnerable is the Space Shuttle to an impact by a small meteor. If a golf ball sized or even a marble sized meteor struck the shuttle, isn't there a very strong possibility of puncturing the shuttle? Would a small hole in the shuttle be catastrophic, causing all the air to escape? Are the astronauts equipped to handle such an emergency? I don't want to hear that the probability of an event like this is low. If you are up there long enough, it will happen.
