Wow, so this is the math that saved Apollo 13. It's an amazing piece of American history.

- Fact 2: Astronauts Jim Lovell, Jack Swigert, and Fred Haise struggled for four days to survive and return their crippled spacecraft to Earth.
- Fact 3: Among the many threats to their survival, the Apollo 13 astronauts faced lack of water, power failure, and carbon dioxide buildup.
- Fact 4: Apollo 13's command module returned to Earth and splashed down safely in the South Pacific Ocean on April 17, 1970.
- Fact 5: Following the Apollo 13 incident, Grumman Aerospace jokingly sent competing contractors a $400,000 bill for "towing" their failed equipment home from the Moon.
