to ma.lee it work. I a.m sure somebody is going to sit down
stairs now and ground check it okay, but, it did not work.
Lovell We did everything and we traded it back and forth to .make
sure that both of us saw the same results.
Borman We had been briefed on this, we used it in the set up
at St. Louis where we had seen how it changed. We had
bad adequate briefings. We had accurate presentations
on it.
Lovell Primarily you could not calibrate the equip.ment, the
reticle would not change fro.m red to green.
Borman We made a couple of measurements where we just used the
calibration lmob at a certain setting and let it alone.
But this equipment was inoperative. I thought it was a
little strange, too, when they called up and said, ''We
have just found out that this equipment is sensitive to RF
interference." "Turn off all your transmitters and see if
this affects it." I think we ought to know before
we go charging into the 3rd or 4th day of flight that
the equipment is sensitive to RF interference. It see.ms
