Lovell No. I did not hear the thrust ers. One reason why we didn't
hea.r the thrusters in t h.at particular case, whereas we did
later on, was the fact t ha.t we ha.d our hoods on and the air
was blowing in and making a l ot of noise. It Wl!.S strictly
by feel and by sight. No sound.
Borman Right. Peri gee Adjuat Translati on. Accel erometer bias was
what they thought it was prelaunch, and it remained that way
throughout the f light. This was a. no platform Perigee
Adjust, so, really that doesn' t have any meaning there. The
timing on the first Peri get Adjust Maneuver was off, thanks
to me. Jim ma.de the maneuver. We did it without a platform
on a. star. And, as I mentioned earlier, about this time we
were in cl ose proximity to the booster, and we started fly
ing through some particles, but I wa.s not sure exactly what
it was, so I told him to stop thrusting as we approached
this. Then, when we got in there, when we stopped th.rusting,
this wire came forward, hi t the hatch, and I lost the timing
again. We thrusted, I guess , a little too l ong. I a.m not
sure exactly how l ong i t was. I think we were aiming for a.
perigee of about 102, and ended up with about 120. M.&¥be
they changed their minds and went for a perigee of 120.

Lovell Well, that time which they gave us was not consistent with
