Apollo 13 incident composite loop is on my website around here:
curiousmarc.com/space/apollo-s-band-communications#h.kuc8m1at9uu4
An even better way to listen to the Apollo 13 audio is to go to:
apolloinrealtime.org/13
Select "join at launch-1minute", then pause it and go to mission time 55:54.
To get an even better listen to the debug, go to the Mission Audio Control tab, and click on EECOM. You'll hear even more of the backroom discussion between EECOM and EPS
The episode about the fuel cell is here:

Corrections:
Since I posted the video, astute viewers corrected a few errors in the video (thank you all)
- the photo of the Saturn IB AS-202 booster being hoisted is not at Stennis for a test, but on launch pad 34 at Cape Kennedy for final stacking.
- the staging footage is the second stage S-IVB separating from the S-IB booster, not from the S-IVB / CSM staging.
- the astronauts were in the MQF for only 65 hours, not two weeks. The MQF was flown back to Houston were the astronauts transferred to special isolation quarters to spend the rest of their quarantine in much more comfort.
