On April 17, 1970, Apollo 13 returned to Earth after narrowly avoiding a deadly disaster in space. This was supposed to be the third mission to land on the moon. Astronauts Jim Lovell, Jack Swigert and Fred Haise launched on April 11 and were two days into their trip to the moon when an oxygen tank exploded, and NASA had to abort the mission. When the astronauts called mission control to report the incident, Swigert uttered the famous quote, "Houston, we've had a problem."
