History for the day: 1970: Apollo 13 returns to Earth

History.com has this for 17 April:

With the world anxiously watching, Apollo 13, an American lunar spacecraft that suffered a severe malfunction on its journey to the Moon, safely returned to Earth.
On 11 April 1970, the third manned lunar landing mission was launched from Cape Canaveral, Florida, carrying astronauts James A. Lovell, John L. Swigert, and Fred W. Haise. The mission was headed for a landing on the Fra Mauro highlands of the Moon. However, two days into the mission, disaster struck two hundred thousand miles from Earth, when oxygen tank Number Two blew up in the spacecraft. Swigert reported to mission control on Earth with the now-famous line: “Houston, we’ve had a problem here”. It was discovered that the normal supply of oxygen, electricity, light, and water had been disrupted. The landing mission was aborted, and the astronauts and controllers on Earth scrambled to come up with emergency procedures. The crippled spacecraft continued to the Moon, circled it, and began a long, cold journey back to Earth.
The astronauts and Mission Control were faced with enormous logistical problems in stabilizing the spacecraft and its air supply, as well as providing enough energy to the damaged fuel cells to allow successful reentry into Earth’s atmosphere. Navigation was another problem, and Apollo 13's course was repeatedly corrected with dramatic and untested maneuvers. On 17 April 1970, tragedy turned to triumph as the Apollo 13 astronauts landed safely in the Pacific Ocean.
