Below find a link to a 27 minute movie filmed before opening the hatch to the Lunar Module showing the three astronauts without there spacesuits helmets boots backpacks on and they are not in site.This could not possibly have been filmed in the small cramped CM named columbia
like I said from the begining I dont know if we went to the moon in the sxties but the record is not factual!!

The lunar surface suits and PLU's were stowed in the LM. So no, they would not have been visible within the CM.  The launch suits and bubble helmets were stowed.  Why do you think it is important that you don't see them?  If you do not believe this video was shot in space, where do you propose it was made and how do you explain the evidence that it was taken in a zero G environment?

Dakdak have you tried looking at any of the numerous cutaways and diagrams showing the actual internal arrangement of the Apollo CM rather than just making wild guesses about it?  For example a search for "Apollo command module cutaway" finds literally thousands of images far better than your attempt at a diagram of it.

...He is my hand wrtten argument color coded

https://dl.dropbox.com/u/81600210/color.pdf
First of all, your entire document is an appeal to incredulity: "Look at all this stuff that has to be in there!  There's no way it could fit!"  You have no idea how large the accomodations actually are, nor any idea how much room everything should take up.  So your argument is unsubstantiated.  Just because you don't believe it - that doesn't prove anything.  Do you have any idea how much room the contents actually required vs. how much they actually had?

Second of all, the answer to your question "where is the solid rocket fuel" for this and that motor is, of course, in the engines themselves.  Where else would it be?  Are you trying to say there is something wrong about the various solid motors?  What, exactly, is your claim, and on what basis do you make it?  Hint: I work in this business.  Don't try to bluff or handwave your way.

Third, your triangular sketch at the bottom makes no sense.  What is the inner triangle susposed to represent?  On what basis did you draw your horizontal sectioning other than your own guess?  And do you now officially retract your claim that the CM is about "6x6x6"?

So, DAKDAK, how much volume do the parachutes and fuel take up? How much volume is required by each component? Where are your quantitative analyses? Where does your figure of 100 gallons of fuel for the command module RCS system come from?

Oh, and to answer a question on your handwritten sheets, the fuel for the solid rocket motor on the launch escape system is in the launch escape tower.

So far your 'proof' seems to reside solely in your incredulity that so many things fit inside such a small volume. Do you actually have any numbers to back that up?

Why would you expect to be able to see them? The spacesuits and helmets were stowed. The backpacks and boots were stowed in the LM, so of course they are nowhere in sight.

And just to add to that, the place where the spacesuits were stowed is NOT included in the 210 cubic feet habitable volume of the crew comaprtment. It's a stowage locker.

DAKDAK, have you grasped the difference between total volume and habitable volume yet?

Quote from: DAKDAK's silly PDF
Forward compartment
In this compartment there was supposedly (3) huge Parachutes and rigging and (2) smallParachute, 2 thrust engines the huge orange ball seen after ocean landing and the 19 inchin diameter Drouge to attach to the Lunar module
Tell us the individual volumes of each of these items and the total volume of the forward compartment.

The Aft compartment
In this compartment there was supposedly 100 gallons of highly toxic fuel but no mention of the oxidizer this fuel required there was supposedly water and helium tanks (10)thruster engines CSM umbilical cord and all the wire and connectors.
Tell us the individual volumes of each of these items and the total volume of the aft compartment.

Wrong.  The PLSS backpacks were only for use on the lunar surface, and as such, were stowed in the LM not the CM.  Tell us the individual volumes of each of these items and the total volume of the crew "department."

Suitable for intravehicular activity in the event of cabin depressurization, yes, but not the full suit and PLSS I believe.

Three suits, but only 2-each PLSS backpacks, LEVA helmet covers, pairs of overshoes and pairs of gauntlets, all stored in the LM.

This isn't much of an "argument".

The solid fuel escape rockets, with propellant, were contained within the launch escape tower. This tower was mounted on top of a "boost protective cover" that fit over the CM. All were entirely external to the CM, taking up no room inside it.

The launch escape tower and rockets could quickly pull the CM (and its 3-man crew inside) away from the Saturn rocket in any serious emergency. It could be used prior to launch, during first stage flight, and for the first minute or so of second stage flight.

The boost protective cover protected the CM from rain while on the pad and from aerodynamic heating during flight. The rocket accelerated very quickly, reaching the speed of sound in about a minute. Without the cover, air friction would burn away the mirror-like coating on the CM needed to protect it from the sun in space. The boost cover protected it until the rocket climbed above most of the atmosphere. Then the launch escape rocket pulled it off the CM when the two were jettisoned about a minute into second stage flight.

You asked about the oxidizer for the fuel for the CM's reaction control systems. Separate tanks for fuel and oxidizer, and the helium used to pressurize them, were all mounted in the aft compartment at the base of the CM, outside the pressurized compartment containing the crew.

Depends on the mission. Every Apollo crewmember always wore a suit at launch, but there were two suit models, one for the Commander and Lunar Module Pilot and another for the Command Module Pilot. From Apollo 7 through 14, the CDR and LMP wore lunar EVA suits with two sets of gas connectors while the CMP wore a simplified non-EVA suit with less insulation and only one set of gas connectors. The EVA model needed one set of gas connectors for the PLSS and another for the Oxygen Purge System (OPS, a backup O2 supply). You can easily see these differences in the crew photos when they posed in their suits. These two suit types were flown even on Apollos 7 and 8 (with no LM and no EVAs) and Apollo 10 (no planned landing and no EVAs).

The lunar EVA suits were redesigned for Apollo 15 for greater flexibility, rearranging the gas connectors. Also starting with Apollo 15, the CMP performed a deep space EVA to recover exposed film from the SIM bay in the service module, so he also needed an EVA suit with two sets of gas connectors: one for an umbilical from the CM (rather than the PLSS used on the moon) and the other for an OPS brought back from the moon for use as an emergency backup. Interestingly the arrangement of the gas connectors on the CMP EVA suit matched that of the earlier (pre-Apollo-15) lunar EVA suit; apparently the greater flexibility of the redesigned lunar EVA suit wasn't needed for an EVA in zero gravity.

Three suits, but only 2-each PLSS backpacks, LEVA helmet covers, pairs of overshoes and pairs of gauntlets, all stored in the LM.
The LM also carried two OPS (Oxygen Purge System) units. During lunar EVA, these were placed atop the PLSS as emergency backups. Although the used PLSSes were jettisoned on the lunar surface, the OPS were carried back to orbit in case they were needed for an emergency spacewalk from the LM back to the CM. They also carried the LEVAs back for the same reason.

On the J missions (Apollos 15-17), the CMP used an OPS and a LEVA, carried back from the moon, during his own deep space EVA to retrieve exposed film from the SIM bay in the service module.

By themselves the OPS and LEVA could easily fit through the hatch and tunnel between the LM and CM. The OPS were tested before lunar liftoff, and had one or both failed the PLSSes would have been brought back instead. So they too could pass between the LM and CM.

As a comparison figure, the manned version of the new Dragon capsule that is under development will carry a crew of seven in a volume similar to the Apollo CM's.

Pressurised volume is quoted at 350 cubic feet, compared with 366 for Apollo.
