t hat they updated our t ime reference system and
had it inaccurately updated by a second .
Yes, I think there is a big fla p about that .
I 'd like to find out about that , too . The r eal
time-transmitter , delayed- time transmitter, stand
by transmitter-- they seemed like they all worked
pretty well . We had no use for the standby
transmit t er and we used the rea l - time and delayed
time transmitter throughout t he flight . You don ' t
have any comments on this, do you?
I 've got one comment . When we came over Guaymas
after our computer went out , and we ' d already
fouled the thing up , I know , they said they wanted
us to come right- side-up for a critical tape dump .
So I did , and I got a message from the ground say
i ng , "Put your Tape Playback to CONTI NUOUS ." So
I put the Tape Playback Switch to CONTINUOUS .
Pretty soon they called up and said , "Do you have
your TM switch to REAL-TI ME and DELAYED-TIME?"
I said, "No, I don't have. You 're going to have
to put it down there." They didn ' t bother telling
me that t hey didn ' t have any command capability
whatsoever . I went ahead and put the Tape Play
back to CONTINUOUS , which means that you're dumping
