that it was adapter batteries. That was the only
abnormal type of indication we had in the systems.
They were all real good.
Well, we had good communications with the ground
during powered flight.
We had pretty good communications.
I called the
"Roll Program", and nobody answered me.
I said,
"Well , to heck with it, maybe they just aren't
ge t;ti.ng through." Then I was just starting to
call Roll Program complete when Gus called and
said,"Did you get the Roll Program?"
Now that was
the only transmission I made that wasn't acknow­
ledged.
Yes, I heard you calling, too.
So , if they lost communications it must have been
right at the 10-seconds t i me , and it should have
been for l ess than 10 seconds. It couldn't have
been for more than 20 seconds.
I heard the count­
down to lift-off and I heard Gus call and ask me
if I had the Roll Program started .
This was a
little bit less t han 20 seconds-- around 18 or 19
seconds.
That is the only period of time I
didn' t hear anybody I should have heard.
So , if
we lost communications, that was where it was.
