probably one of the weakest points in our flight
planning-- trying to get times correlated .
This correlation between one time and the other
time is hard to handle.
We were getting start
times in GMT.
We sai d that we wanted these start
times in GMT because this i s the only official
time that we had.
The elapsed times were just for
planning.
We only kept them to the nearest two
or three minutes .
I started my Omega watch on
elapsed time at take-off, and I just let it run
through the whole flight.
I never set it.
I
never checked elapsed time or anything. It could
have been off two or three minutes , but I was
doing the flight plan to the nearest iO minutes
off the book here.
When we got retrofire times
and when we got start t imes for things, we got
them in GMT .
It made it awfully confusing in the
flight plan by switching back and forth,
Fortunately, we got off at 15:15 which is better
than getting off at 12:36 or something like that.
On the Apollo mission we 've got a better set of
clocks .
We're going to have Mission Time and
Phase Time , so whenever you start a new phase
