They may have decided on the 45-degree angle after Apollo 9 and before Apollo 11, since they did a lot of experimenting during the program. The panels weren't detached from the booster at all during Apollo 7, but Wally Schirra complained that the panels were flexing too much, posing a danger to the spacecraft when it docked with the LEM during the transposition maneuver. >>The Apollo 15 >>article I referenced indicated that the panels were jettisoned >>when they were rotated on their hinges 45 degrees from the >>booster axis, so I assumed that they were ejected at that same >>angle to avoid a large part of the force of the springs just >>causing the panels to tumble rather than move away from the >>spacecraft.

It would also put the panels behind the >>spacecraft, while the UFO was sighted in the forward direction. >I do not see where it is stated that the UFO was sighted in the >forward direction. They said it was tumbling and that it was >"going by". In the book _First Man_ Neil Armstrong gave his own version of the panel explanation. He said one of the panels was off to one side but had gotten sligthly ahead of the spacecraft at a position where it would reflect a large amount of sunlight. But Armstrong was speaking from memory years after the mission. He was also recollecting how they knew at the time the object was probably one of the SLA panels but didn't want to say anything that would excite the "UFO nuts" at the time. That seems to be a rather odd explanation, since if they knew it was a booster panel and had just told that to mission control, the UFO nuts wouldn't have gotten terribly excited. In any case, the debriefing transcript indicated that Aldrin had already considered and rejected the SLA panel explanation at the time and that Armstrong didn't object, so he seems to have misremembered what they knew and didn't know at the time. So perhaps Armstrong's memory was innaccurate on the position of the object relative to the spacecraft, too. >But the odd thing I just noticed in the Mission report is that >during the time the object was sighted, the spacecraft was in >passive thermal control mode.

If the spacecraft had been rotating a full 360 every 20 minutes, it seems to me if it were a piece of debris from the spacecraft itself, they should have been able to observe its progress as it moved away from them and concluded it had originated from the spacecraft. They also should have been able to discern its shape without using the telescop when it was closer to them. I'm not saying that proves anything, though, since they just might not have been paying enough attention to have noticed a piece of debris when it was closer to the spacecraft.
