APOLLO 13 EARTH ORBITAL CHART | Artsy
Some nice catalogue details around this Apollo 13 AEO:
Apollo Earth Orbit Chart (AEO), Apollo Mission 13 for April 1970 Launch Date. March 3, 1970. Color Earth map, first edition. 13 by 42 inches.

From the Catalogue:
SIGNED and INSCRIBED: “JAMES LOVELL, Apollo 13 CDR and FRED HAISE, Apollo 13 LMP." Additionally INSCRIBED by HAISE with mission events: "Launch at 2:13 pm EST, April 11, 1970" and "Splash – April 17, 1970." He has marked the splashdown area with an "X."

Circular plots in black represent the ground station communication coverage areas with the red circle being the tracking ship Vanguard in the Atlantic Ocean. Orbital paths show the full launch range azimuths of 72 to 108 degrees. The first orbit is plotted in light blue with the second orbit in dark blue. The planned TLI (TransLunar Injection) burn occurred on time during the mission and is plotted with a red dashed line. The point above the Earth as Apollo 13 headed toward the Moon is shown with a brown line and continues for 24 hours of mission elapsed time. This line moves over the Pacific Ocean and into the continental United States. Then it moves backwards (relative to the Earth’s rotation) over the Pacific Ocean and ends near the west coast of Africa. The Service Module explosion occurred some 32 hours after end point of the TLI brown line tracking plot.

How Curiosity, Luck, and the Flip of a Switch Saved the Moon Program | Motherboard
"SCE to off?" someone said. The switch was so obscure that neither of his bosses knew what he was talking about. "What the hell's that," blurted out Gerald Carr, who was in charge of communicating with the capsule. The rookie flight director, Gerry Griffin, didn't know either.

Sixty seconds had passed since the initial lightning strike. No one else knew what to do. The call to abort was fast approaching. 

Finally, Carr reluctantly gave the order in a voice far cooler than the moment. "Apollo 12, Houston, try SCE to Auxiliary, over."
