Charlie has all of the quotes in his computer book that show how nasa pretended to not have any idea where the eagle was and here are some of them
from the donald beattie "taking science to the moon" book
"In the meantime we were monitoring the signal sent back by the passive seismic experiment and attempting to find the LRRR that the astronauts had
left behind. This latter operation was not as easy as we expected, since the exact location of the landing site was not immediately known. Mike
Collins had attempted unsuccessfully to locate the LM from orbit using the command module sextant. After analyzing the flight data and the returned
photographs, we passed our best estimate to the LRRR PIs, and the LRRR was found on August 1, 1969 by the Lick Observatory in California."
this is from the world famous andrew chaikin he wrote this in "a man on the moon"
"But no one, not Armstrong and Aldrin nor anyone in mission control, knew just where Eagle was. The location would be a helpful, though not
essential, piece of information for this computer to have during tomorrow's rendezvous. It fell to Collins to try to find the LM on the surface,
using the command modules 28 power sextant."
and then andrew wrote this to in that book
"Each time he(referring to Collins) went around from the far side, mission control had a new set of coordinates for him to try, but on his map, one
guess was as much as 10 grid-squares away from the last. It didn't take long to realize no one had a handle on the problem. His search continued
fruitlessly for the rest of his 22 solo hours."
michael collins wrote this in "carrying the fire"
"Of course the ground can take its measurements as well, but it really has no way of judging where the LM came down, except by comparing Neil and
Buzz's description of their surrounding terrain with the rather crude maps that Houston has."

CDR.(TRANQ) "Houston, the guys that said that we wouldn't be able to tell precisely where we are are the winners today.
We were a little busy worrying
about program alarms and things like that in the part of the descent where we would
normally be picking out our landing spot; and aside from a good look at several of the
craters we came over in the final descent, I haven't been able to pick out the things on
the horizon as a reference as yet."
Leon wagner wrote from "neil armstrong's stellar american journey" and it is not american so fony
"While Houston and Eagle prepared for liftoff, feeding coordinates into the computer that would, with luck, achieve a smooth rendezvous with Columbia
on its twenty-fifth lunar orbit, there were two nagging worries. One was a slightly embarrassing technical failure: Houston wasn't precisely sure
where Tranquility Base was located on the lunar surface. Ever since touchdown, NASA's geological survey team had been scrambling to unravel just how
far away from the planned landing site Neil had gone while scrambling to avoid the deadly escarpment.
The United States Geological Survey in Houston and the Center for Astrogeology in Flagstaff, Arizona, desperately studying maps and analyzing
information available, had finally come to a consensus. But it was just an educated guess. There had been no provision for an aborted site and a
zig-zag, last-second dash to find a safe landing zone. The one hope for a completely accurate fix was the laser retro-reflector experiment Aldrin and
Armstrong had assembled a few hours prior. But, thus far Houston hadn't been able to locate the reflector with the laser.
Less than an hour prior to scheduled liftoff, Capsule Communicator Ron Evans apologetically briefed the astronauts on the situation: "We have fairly
high confidence that we know the position of the Eagle. However, it is possible that we may have a change of plans. But in the worst case it could be
up to 30 feet per second, and of course we don't expect that at all". Meaning: If they were far off Eagle's location, a successful rendezvous would
require some quick and accurate throttling up or down to thread the needle properly tricky work at 5,000 miles per hour. Of course, it was for such
contingencies that Buzz Aldrin, a man with a genius for astrophysics, who held a Ph.D. in space rendezvous from the Massachusetts Institute of
Technology, and Neil Armstrong, one of the coolest hands in the history of aviation, were chosen for the job. NASA believed the Apollo 11 team could
do it, and so did they. In the end, NASA's failure to ascertain the exact location of Tranquility Base had no great impact on the docking of Columbia
and Eagle, which was fortunate, because it wasn't until 5 days after splash-down on July 29, when film taken by the astronauts was processed and
studied, that an official determination was reached."
