Now about the lem.
The lem could of had a redistribution of weight at any time, it would be enough for astronauts to move a bit inside and change the distribution of weight to the side.The lem could also on it's weight upside down, it could also move too much to the side and go in to free fall, at such speeds I doubt the lem could make it with vertical thusters.
With a total weight of 2 tons falling at 10 feet per second, and in the last stage at about 4 feet per second I doubt the lem wpuld pull off a soft landing.
pepsi, the LM had two men, who did not move around during the de-orbit burn, to plan a landing on the Moon.
What is more, and you can research this if you like, the craft had, on each for corner, a FOUR valve thruster THAT...wait for it!!!
Could actually thrust, as needed, to control the vehicle. See, no need for aerdynamics, it's all Newton.
Picture this...and please, look it up, don't take my word, this is too easy to find out for yourself...
Here's a vehicle....four thrusters, times four...since there are FOUR THRUSTERS equidistant around the vehicle....that means there are SIXTEEN ways to control the spacecraft....
THIS, combined with the MAIN Descent engine to use, at first, to change orbit...and the attitude thrusters are used to maintain orientatiion....the MAIN Engine is used for altitude control....this has been well planned out by Mission Control....they know how much fuel is available, the sensors transmit the data, the Astronauts know, since they SEE the gauges. There is a time delay, of course, from the Moon to the Earth...and back. IT results in some misunderstandings....but that is because Radio travels at the... Speed of Light...and a round trip radio signal, even at 186,000 miles per second, still takes about 1.7 seconds (and thats just allowing for light speed, not to mention Human delays...)...
Finally, I hope someone can come along and point out here, how completely SILLY the post was. I am sorry if this vilolates T$Cs, but there is a point when we just have to stand up and cry "FOUL"!!!!! on someone!!!

There are factors that you are not taking in consideration, when there is descending speed and horisontal speed such a device becomes extrimley hard to control, it had to corect it's balance when it moved left and right , all it had was little jet thusters, but never mind the moon, such a craft is not operational anywhere , moon, mars, earth, can you imagine controling such a craft manualy at 4 feet/ sec descending speed?
Do you think the lem was some sort of bouncing doll that came back to it's possition.
This does not matter any way, you know why? because there is no evidence that such a craft can function.
A 2 ton cube manualy controled at 4 feet per second going down.
Please show me a 2 ton descending at 4 feet per second and thenlanding.where is the video?
In stead you give examples of light drones landing on the moon that weight X-times less than the lem or you show lame air devices built by nasa that take off and then upon stoping in mid air with out any descent speed aply vertical jet power and then land on the ground ..instead of all of this why don't you show us the video, guide us to you tube and enlight us.
Facts,
1 No other space mission went above the van alen belts except the apollo missions.
2 No version of the original lem was tested before the missions.
3No other kind of craft as the lem was ever tested as in droping it from orbit and then landing it with it's 7 tons, as the lem had a weight of 2 tons on the moon, on earth I would be happy to see a one ton sort of craft droped from earths orbit and then see it land.
4Nasa to this day keeps having problems failing with lame crafts that use low speed where the craft takes of fand then lands ? or crashes?
5If nasa can't get it right and we are in 2008 what guaranty do we have that it worked at that time when one of the test vehicles crashed just before apollo 11 when armstrong ejected.

part '2' pf your post...LMs were tested, on Apollo 9 and 10. Apollo 9 tested the LM in Earth orbit...10 took it to the Moon, to within 10 KM of a landing.
The LM was the only component of the entire Apollo Program to never suffer a major failure.
In fact, LM worked with out problems for Apollo 11...even though the crew broke off a circuit breaker head...they found a solution to get home.

How do you test a landing module in orbit? how about droping it from orbit? you know landing it?
Regarding apollo 10 testing it on the moon has 0 credibility, sice the moon missions them selfs are in doubt .In the end none of them preformed landings.
You still can't prove they fully tested the lem, plus the fact that the lem was tested on the moon half way , it's like making some one that does not believe in the moon landings accept the fact that it was tested on the moon.
The whole point of this debate is if they went on the moon, and you are comming and telling me they tested the lem on the moon, to my opinion it would of crashed.
How do you know?because they told you?
They told you it worked perfect, and you accepted it.
I don't have to.
This is what they told you, but but but.....how can it be proven? can you prove the moon landing?
I do not beilive any of this because I do not know if they tested the lem on the moon, I do not know if the lem landed for real on the moon, and I do not know if they played golf up there, just because they say everithing was okey dokey is not enough, acording to my own toughts I think for example the test lem used on the apollo 10 would of crashed just like the others simply because of the speed of the object in an inviorment where gravity is present but there is vacum.
If they would of tested the lem on earth as in drop it from orbit and land it , then I would of told you..I rest my case.
Regarding me as leaving soon,as I'm some one that you think I am? I do not have any idea what you mean by that, I've been here as an active member on this lovley international forum form 2005, and I've participated in this thread long before you did.
You didin't even bother to comment on the other points, that is because you have no arguments on them.
cheers
Chapter 6:
THE GRAND FINALE
Apollo 5 was launched on 22 January 1968
with the primary objective of testing the lunar
descent propulsion; the ascent propulsion, including
restarting capability; the spacecraft structure;
the instrumentation and control; and the second
stage of the Saturn IB. After separation from the
Saturn booster, the Lunar Module was in an elliptical
orbit and proceeded with a test of the descent
stage. The planned 39-second burn only lasted 4
seconds due to a computer program glitch. The
ground controller shifted to an alternate plan and
tested the descent stage first with a 26-second burn
at 10-percent thrust and, finally, a 7-second blast at
maximum thrust. Later, each stage was put through
its paces, ending with an ascent-stage firing of over
6 minutes.
The descent engine was throttleable, like that of
an automobile—the only rocket motor with this
capability, which was necessary for a soft-landing
on the lunar surface. Ignition of the ascent engine
was essential to recovery; there was no redundancy.
For this reason, hypergolic fuel was utilized—ignition
occurred without the need for a separate firing
source. In an abort, this stage had to ignite and fire
even while the descent stage was still providing
thrust. During the test, the so-called “fire in the
hole” was successful. The flight was judged satisfactory,
and the Lunar Lander was declared ready
for manned flight.

Watch the documentary "A funny thing happened on the way to the moon" and actually be conscious and un bias because the evidence is real. You can find it on Youtube and Google video.
1. Where did they go?
They stayed in Earths lower orbit due to the fact that 1960's tech could not protect them from radiation.
Oh, and the Van Allen Belts? The good Dr. van Allen HIMSELF said, before he died (guess it would be more difficult to get a quote from him after he died...) that the radiation was not fatal, in a limited dose.
And...the Moon's surface is radioactive???!!!??? That is just plain silly...as is most of what you try to believe....
The gamma rays from the Moon do not come from reflected gamma rays of the Sun. Instead, high energy particles (mostly protons) that are travelling very close to the speed of light, called cosmic-rays, continuously slam into the Moon. When these particles collide with the lunar surface, they react with the particles in the Moon's surface, exciting them and generating gamma rays. This process is similar to what goes on in particle accelerators on Earth.
When galactic cosmic rays collide with particles in the lunar surface, they trigger little nuclear reactions that release yet more radiation in the form of neutrons. The lunar surface itself is radioactive!

We are talking about X rays, Gamma rays, residual radiation on the moon, and particles hiting directy, and yes it is that bad when you are exposed to radiation and the dosage will add per hour, in fact my previos posts on the mater failed to specify that radiation is a cumulative factor.
Now as I know x rays and gama rays are stoped by thick led shielding.
