Apollo 13 :-)

The most dangerous mission in the history in NASA.When they went up into space the launch thing was destroyed in space.The whole right side was destroyed. So the people at base at Houston were trying to find a way out to make them go to the moon.So the bottom line is that they needed to get the astronauts back to Earth.The magel was suppose to only land on the moon but they needed it to take it to the atmosphere.They made it back safley and the president made a ceremony.
