How was it possible to hear Aldrin, or any other astros, while the engine was blasting?
If they had on their suits:
1. How effectively could they have controlled the craft?
2. How could the suit work in a pressurized environment?
If they were not wearing their suit
1. How could you hear Aldrin so clearly?
Here is the problem:

In NASA spacesuits, communications are provided via a cap worn over the head, which includes earphones and a microphone. Due to the coloration of the version used for Apollo and Skylab, which resembled the coloration of the comic strip character Snoopy, these caps became known as "Snoopy caps".

There is no sound in the vacuum of space remember: "In space no-one can hear you scream?"

Ok but, what does the vacuum of space have to do with the inside of a cabin?
You realize that there were microphones inside the helmets? In fact, the microphones were part of the "Snoopy hat," a lightweight cap worn under the helmet, or on it's own in a "shirtsleeves" environment.

So were they wearing their suits or not?

BTW, may I ask a simple but straight question..? FoosM, are you Jarrah White? I note you registered 5/5/10, and have posted nowhere else but here...

This snoopy cap with mic does it have some kind of technology that reduces vibration in an astronauts voice during ascent and descent? Does it also drown out other sounds from inside the cabin? Why is this technology used wit h the shuttle astronauts?

I refer you to Weedwhacker's post above.

Incidentally, in order to head you off, the structure of the craft did transmit vibration. Use of the attitude control jets did often lead to a distinct "thump" sound in the cabin.
Apart from not realising that operating in a vacuum means there was none of the atmospheric noise transmission (which means of course that the ONLY noise that could reach the helmet/microphone was that transmitted through the astronaut himself...), it seems you have also forgotten that this was in 1/6 gravity.

No, it doesn't... that's why you hear the astronauts' voices so poorly during lift-off, when the atmosphere causes so much vibration. In space, of course, there is no atmosphere, and the thrust from the CSM and LM is negligible.

What do you mean "drown out other sounds from the cabin?" Do you think they've got a juke box blaring up there?

My answer is the same as Weedwhacker's, he's just a bit more specific. No, we don't disagree.

You just stated there were sounds in the LM (from engines)
do you retract that statement?

Did he tell anyone? Did he tell American public? Announce it to the world?
If he knew, why didn't he warn the Japanese?
So was the Manhattan project a secret or not according to your definition of secret?

Where did I say that, exactly? I said that sometimes you could hear a "thump" from the attitude control jets. This was in the CSM when the module was pressurized.

Again who cares if Stalin knew or what claimed he knew.
It was still a secret wasn't it?
Did the American people know?
And who did the US bomb? Russia?
Did it ever occur to you that maybe the USSR also knew that Apollo was faked?

So are you now saying that the LM during descent and ascent was not pressurized?
