In astronaut Mike Mullane's book Riding Rockets, he talks about a payload specialist who flew on an early Space Shuttle flight that put everyone on edge. When the guy was training he found out that you can open the side cabin hatch while you're in space, and nothing would stop you from killing the whole crew in seconds, and he kept dwelling on it. After that the mission commander was given a lock and key, and as soon as the vehicle reached orbit the commander would go lock the hatch and leave it locked until everyone was strapped back in until landing, for the rest of the Shuttle program.
