Check out this transcript.  Notice that PA makes no mention whatever of the
problem?  I remember (and actually heard in real time) the "Program Alarm
1201" calls (and was worried before Walter and Wally noticed, as I recall)
on Apollo 11, but I don't remember the SCE to Aux call at all.  They must
have switched it back before TLI, right?  Surely they would not head off to
the moon with no backup...

Burns, W2BFJ
(who also knew they had landed before Walter..."Contact light...engines
stop."  Wait several seconds, they are still talking.  They must have
landed!)
