there is no rain on Pandora, yet lots of clouds and wildlife and rivers! Keheeeeeeeeeeeeeee!

Good observation but Pandora must have rain, In the night when he is in the tree. When he was making that video. And the last possible sign is the cloud in the floating mountans

There were scenes in there when Neytiri and Jake are in the forest and the atmosphere is quite damp and the sound hints that it rains. While there where no scenes that directly show rain(maybe because it was too labour intensive to do) there are few that give hints that pandora does indeed have rain.

the first two 'goofs' on imdb are wrong. <_<
first of all, the avatar(s) wearing clothes aren't Norm, they're the other avatars, the ones we saw at the beginning.

second: we can see na'vi having 4 toes and fingers, but avatars (being made from human dna as well) have 5 fingers, 5 toes (and eyebrows, which the imdb-poster failed to mention)

the first on has some sence but because of the human dna in the avatars the 5 fingers and toes, smaller eyes, and eyebrows appear. good going on the first one though.

Now one of the avatars could be Norm.(unless he is seen as a human, I cannot remember)Because his avatar was only shot in the arm and the shoulder. And we see Norm going out into the jungle as himself after his avatar was shot, he very well could have gone to look for his avatar and nurse its wounds. Atleast this is what I think.

at the very end you see norm and the other scientist standing there next to the na'vi (and they are wearing masks ) overlooking the people leaving in the ship. they were one "of the few chosen to stay". or something like that

Norms avatar was shot, and he left his "DRIVER POD", the next time we see him near the end when people are leaving, he (sans avatar) is standing next to Max, Jake, and Neytiri.  The human clothed avatars are other human drivers from the program in their avatars, clearly different looking faces.  The Avatar link room had many pods, more than just the three main Avatar drivers from the film, and there were many drivers outside excersizing and practricing, thiss leads me to belive there may actually be several drivers still on pandora.

Yes, Human Na'vi hybrids have Five fingers five toes, pure Na'vi have four fingers, four toes.  Thanks to Cameron's foot and hand focuses, we can see this detail distinctly, in the first link sequence with Jake and Norm, when Jake is seen running for the first time, when we are shown Neytiri for the first time stalking Jake you can see her feet and hands closer.

when the dragon punches quite a few holes through the windshield of trudy's aircraft, she has no trouble breathing without the mask.

i don't know, i'll have to watch the scene again, but the clothed avatar in the end looked like norm to me. (although just a second before that shot, norm is viewed with mask in his human body).

yeah she does seem to be able to breath after her ships gets shot up,
also those dragon gunship clearly do not have separation between the cockpit and the passenger area. in fact in one scene when they have a shot of Trudy flying it you can clearly see in the background the outside world, with apparently no intrusion.

In regards to the atmosphere, i don't think it's actually poisonous, just lacking in O2.

While there where no scenes that directly show rain(maybe because it was too labour intensive to do) there are few that give hints that pandora does indeed have rain.

It was most definitely raining when Jake made his clean kill and Neytiri said he was ready.  Not just hints, but when the angle was right you could see the rain.  When he's making the video log entry before that, of course, it is also raining outside.

In regards to the atmosphere, i don't think it's actually poisonous, just lacking in O2.

I would disagree.  Assuming that the native biology is similar to the terran counterpart, there are some creatures there which will need some serious aeration to their body.  The ikran, for example, have a means of breathing that is more to helping them fly than it is to getting oxygen, so to evolve in such a way as flying efficiency is favored over breathing efficiency, one would have to assume that getting oxygen out of the atmosphere is not the problem.

Furthermore, larger creatures tend to thrive in an oxygen rich atmosphere.  That is why the dinosaurs grew so large; the earth at the time had much higher oxygen concentration in the atmosphere.

So I'm inclined to believe it's something else in the atmosphere.  On earth, we actually have a nitrogen atmosphere, not an oxygen atmosphere.  There is around 4 times the nitrogen as there is the oxygen.  And the co2 is relatively minor in comparison to both.  If the primary composition of the Pandora atmosphere is not nitrogen but something else, it could certainly cause issues with our terran biology.

[MaTe]

definitely poisonous. you are good 1min+ without o2 (and it is shown in movie when they hold breath). Though when they inhale - 20 seconds and convulsions start.

hmm what leads me to believe that it's oxygen is how Jake reacted when he was breathing, which seemed like a reaction to rapid hypoxia. If the air was oxygen rich, hypoxia would not have occurred and therefore his rapid seizure like breathing in said scene would not occurred either, also if any other gas were present the person would not notice the lack of oxygen and would simply become dizzy and black out (as has occurred in atmospheres with excessive nitrogen or carbon dioxide/monoxide) if it where more dangerous gases, the person would have started coughing.

As i have read in pandorapidiea, the internals of the na'vi are quite different then our own, (in fact they use a type of protein structure rather then DNA or RNA to transfer information.)
therefore, it could be concluded that oxygen may not be used. Size may actually be attributed to Pandora's lower gravity, and an increase in lung/ equivalent to lung, would allow them to operate in a low pressure environment. ( or perhaps breathing is not as important to them)

in addition, it seemed like the atmosphere lacked pressure, evidence namely being when sudden openings where formed i.e. col miles kicking of the door resulted in a sudden (what seemed like) depressurization. 

[MaTe]

they claim air is thicker on Pandora than Earth.
I'm not a doctor/biologist. Can having high concentration of oxygen cause "lung burn"? I know they use pure oxygen for diving.

[Roiki]

In diving they don't use pure oxygen actually, but oxygen-nitrogen mixture, and in some cases other gasses, oxygen alone can't go very deep. What i thought is that Jake had a central nervous system reaction to oxygen toxicity, which occurs when one breathes greater concentration of oxygen at a higher than atmospheric pressure in a short amount of time than a human is accustomed to. The symptoms include convulsions and unconciousness.

The airlocks in Hell's Gate opened outwards, which supports higher atmospheric pressure since that way they don't need locks to stay closed, similiarly in many scenes it shows how the outside air goes in rather than the inside air going out, suggesting that they have negative pressure inside their buildings.

[Toruk Makto]

The arrows look like they have chipped stone heads. So, with the size of the arrows (huge!), extra velocity of a dive, possibly thinner windshields on the smaller kunsips and what looks like more perpendicular hits, I find it plausible that they could penetrate that way.

[Toruk Makto]

The "Survival Guide" says that the air is high in CO2 and Xenon creating the toxicity, but the partial pressure of O2 is the same as Earth (less nitrogen?). Things burn "normally" there, so that would seem to bear out the presence of a similar O2 fraction as Earth.

Divers can be trained to breath up to 100% oxygen. But this is not the case with recreational diving, as they use a mixture of nitrogen and oxygen, (sometimes helium) and oxygen, as you said.
The risk lies when we have increased atmospheric pressure, but even when the atmospheric pressure was 3-3.7 times that of earth, the onset of convulsions varied greatly from individual to individual (16 mins to 92 mins)[as shown by experiments done by Kenneth W. Donald] though now we have limited diving to operate between 1.2-1.6 bar.
Certainly not the 40 seconds that was stated in the movie.

another problem i see with this is the fact that such a plant rich environment would not exist in high oxygen concentrations(plants use primarily CO2 for photosynthesis), so the limit of 3.7 atmospheres would be raised if less % o2 existed (there have been deep sea divers who have worked at 33x earths atmosphere)

[Reronsem Si]

Watching the movie again and again, I at first believed that the Cargo aircraft (Based off the CH-60 from the fuselage) had an open cockpit to the passenger cabin, BUT it doesn't. If you look closely on shots where they are heading to the Hallelujah Mountains, you'll see a metal/glass door sealing the atmosphere in the cockpit.

To help explain when Trudy gets shot at and she doesn't gasp, typically you have a higher pressure atmosphere inside the aircraft or cockpit than outside. Keep in mind the pressurization is most likely 1-2 psi greater than outer atmosphere, since you would want higher pressure inside to prevent the toxic gas coming inside if there is a leak. Since the glass seems to be the type like safety glass, the holes that were created were very small and most likely didn't depressurize the cabin rapidly, so the toxic air was unable to seep in. She didn't survive too long anyway, so it's hard to tell. If you look at the Col.'s glass for his Amp Suit, it did the same thing with the bonnet. It surrounded the knife rather than shattering and this reduced the depressurization of the cockpit.

The cockpit glass flying way out of reach isn't due to weaker atmosphere or much higher pressure in the cockpit,  but rather safety for the driver. Like the ejection sequence for a military jet, the canopy was most likely lined with explosive bolts and made to have a trajectory away from the suit so that it will not impede or create a hazard for the driver.

i don't know, i'll have to watch the scene again, but the clothed avatar in the end looked like norm to me. (although just a second before that shot, norm is viewed with mask in his human body).

It is definitely not Norm I paid attention to that yesterday. It is, if I remember correctly, the guy from the beginning who played basketball with a female avatar outside on the training field.

[Toruk Makto]

Norm's avatar looked like it was shot in the shoulder. I wonder if the wound was actually fatal, or is the avatar body just in the hospital healing?

[Reronsem Si]

If it was anything "instant fatality" then we would guess Norm would be dead as well. Course this would have to bring in The Matrix ideas, about how death in the mind, or in this case an avatar, would also spell death in reality. You can sense the danger of being killed while in your avatar because Grace is worried about Jake while he is stuck in the forest overnight. If she was only concerned about the cost and the time it takes to get a new one, then her attitude would have be more of a selfish brat having a tantrum. Instead she acted as if a new colleague was about to die and her concern was for his safety.

Also Norm's avatar gets shot on the side of his ribs and his shoulder. He immediately goes for his own shoulders when he gets out of the sync. In my opinion his avatar is alive and will be back for round two!

i think that perhaps they didnt know what would happen if your avatar died while your connected.
