I can't believe that I've never heard about this, the real potential deaths of Apollo 12 astros Pete and Al. From the page with the discrepencies noted above...

- The VHF radio voice link between the LM and CSM completely failed during
crucial parts of the rendezvous. This was labeled by the crew during
debriefings as a completely unacceptable situation, because the CSM was
supposed to be prepared to perform mirror maneuvers to the LM's maneuvers if
for any reason the LM couldn't make its planned maneuvers. Many of these
maneuvers occurred on the back side of the moon, so the confirmation of LM
maneuvers couldn't be relayed to the CSM from Houston. The CMP had to just
assume that the LM had made the proper maneuvers. Had the LM failed to make
any of the scheduled burns, the rendezvous would probably not have been
accomplished before the LM ran out of consumables.

This is amazing. What do we know about this? I'm also going to post this at Project Apollo.
