54 years ago, at 10:06 PM EST, Monday, April 13, 1970, the #Apollo13 Mission Control heard these fateful words:

055:55:19 Lovell: ...Houston...
055:55:20 Swigert: ...we've had a problem here.

055:55:26 Fenner (GUIDO): FLIGHT, GUIDANCE.
055:55:27 Kranz (FLIGHT): Go GUIDANCE.

055:55:28 Lousma: This is Houston. Say again, please.

After 4 days of hardships, heroism, improvisations and ingenuity, the crew landed safely on Earth.
