On Apollo's docking system whenever they transfered between the vehicles they had to remove the probe by hand right completly? So when the two got into the LM before going down to the moon the Command Module Pilot had to put the probe back in the tunnel before closing his door right?
So anyway after the lunar landing and rendevous and docking and after another transfer again of taking the probe out of the tunnel did they put the probe back in before the final undocking which blew away the docking system itself? The probe was attached to the part of the command module docking ring that was jetisoned on final undock? Or did they leave the probe actually inside the lunar module itself. And also is did they use the final undock of the LM like the space station does with Progresses when they are through with them. Did they throw everything like the trash they had accumulated so far in the mission behind in the LM. Seems like it would be a good way to get rid of everything in the Command module you don't want to haul back to earth with you.
Ok its a lot of questions. LOL. Just really curious about all this.

I believe the LM jettison sequence did leave the probe and drogue behind with the LM. It wasn't necessary to install them in the tunnel and they're not visible in pictures of the hatch of the jettisoned LM so I suspect they just tossed them into the LM cabin with the rest of the trash, just as you say. Getting rid of unnecessary weight before the TEI maximized the delta-V attainable with the SPS.
Mike Collins wrote in Carrying the Fire that his probe assembly really seemed to have it out for him, and he was most happy to finally get rid of it.

That gets me wondering, was there a contingency plan for the CSM pilot becoming incapacitated when the LM was away?

Well the lunar module actually had a small docking window in the top of it but I don't think the lunar module was ever the active craft during the docking was is? It was always the command module pilot making the dock from the command module?

The LM was the active vehicle in LOR because its guidance platform was better. It had finer-grained accelerometers that gave better intermediate solutions to the rendezvous steps.

Would the LM crew blow the incapacitated or dead CM pilot out the CM hatch so that the LM crew could then safely return to Earth? If it had to be put to a vote, would the LM crew would win the day?

So really, the only thing the CM pilot had to do was open the door once they were docked?

Would the LM crew blow the incapacitated or dead CM pilot out the CM hatch so that the LM crew could then safely return to Earth? I can't see why it would be necessary to throw the dead man out when the CM is a three man craft. He's not taking up any extra room. OK, so it won't be a pleasant journey home with a cadaver strapped down next to you, but I can't see what would require them to chuck him out rather than bring him home to his family.

Throwing one of the astronauts out would in fact throw off the weight balance of the CM and might result in the surviving two burning up on reentry. I am reminded of the scene in Apollo 13 where they had to transfer "ballast" from the LM to the CM to compensate for the missing lunar rocks.

I am reminded of the scene in Apollo 13 where they had to transfer "ballast" from the LM to the CM to compensate for the missing lunar rocks. That was necessary because NASA forgot that the CM wouldn't be returning to Earth with moon rocks, yet they picked up on this when they realized that AP13's trajectory didn't quite match what was expected after a flight course correction burn. I was just joking about having to toss an astronaut overboard, but what if a LM crew member really did have to depressurize the CM and then blow the CM hatch in order for the LM crew to gain entry into the CM because the CM pilot already was dead? That was my point, along with possibly a shortage of CSM fuel, without dumping some mass, for return to Earth? Y'all sometimes takes posts way to seriously instead of seeing the implied humor.

As I recall, the entire rendezvous and docking maneuver was piloted from the LM. Mike Collins says in his book, Carrying The Fire: The rendezvous manoeuvres, carried out by the LM, are listed in the Apollo 11 Press Kit, published before the mission. Actual times were close to those stated:

Thanks thats what I thought that the CM pilot actually did the actual contact and capture from the command module even if the LM was the active vehicle during most of the rendezvous.
