How did the Engineer survive the planets atmosphere ?

These are someother posts on the subject, might have the answers you are looking for; (One was posted yesterday). -[url=http://www.prometheus-movie.com/community/forums/topic/10412]Helmetless Space Jockey[/url] -[url=http://www.prometheus-movie.com/community/forums/topic/7606]Engineer going to lifeboat[/url]

Sorry, did not see these. Thanks.

They actually were terraforming the entire planet as Holloway hints, and David restarted an ancient atmospheric processor improperly when he opened that door. That's my theory, what I choose to believe based on what I know, and I'm sticking to it.

Oh and since the Engineer would then know the facility was active again he could have assumed he would be able to breathe outside and that terraforming of the planet had resumed. The storm / atmospheric disturbance above occurs directly after the disturbance in the room below.

It's not a causal relation for certain, but there is a temporal correlation and certain trend in the data. So there could be a causal link between the two atmospheric changes that occur together, or other variables that are affecting both. I.e. the goo/ toxins in the air...

No, we don't know that at all. Fifield, although mutated perhaps to some advantage, managed to breathe ok.

or maybe he was so dead he didn't need to breath? Like T-Virus in RE. . .

That's a nice trick if you can pull it off, but it's only going to antagonise the people who want a plausible scientific explanation for everything!

--- Only if you’re breathing thru an exhaust pipe. CO2 is over 3%. Two minutes without a suit, you’re dead. --- Yeah. Look at the CO2 levels. Outside it’s completely toxic and in here it’s nothing. It’s breathable. --- This is wrong? From wikipedia... "CO2 is an asphyxiant gas and not classified as toxic or harmful in accordance with Globally Harmonized System of Classification..." In higher concentrations 1% (10,000 ppm) will make some people feel drowsy. Concentrations of 7% to 10% may cause suffocation, manifesting as dizziness, headache, visual and hearing dysfunction, and unconsciousness within a few minutes to an hour.

Toxic atmosphere for humans...so another thing is, that mutation/suit we see on the alien guy could sustain him for a time on such atmosphere... They need an atmosphere like ours to live normally, but could sustain themselves at least for a time under dire atmospheric environments (he is a soldier, so should be though to begin with)

they are not like humans.....period......so what they can take and what humans could were completely diff....remember we are a weak race...period..they made us for one thing and one thing only...to grow up and die as a result of being vessels in our adult life to let the ALIEN burst from our bodys for the hunt.....maybe i can use this quote from AvP...."the came back every 100 hundred years for the hunt"....and which in AvP there were dozens of temples so a lot of humans died...so they had to give us time to reproduce or "soft" society.....so i would have expected a Jockey to hold some reserve air in his suit....without his helmet....

Assuming that they made us just for being vessels of the bugs is assuming too much. A million or billion years investment just for that is way too much, and also inverts the things a bit. The bugs are a war tool, a bio weapon, a tool they made, and then they would made another tool to work for their weapon after a billion years? ... There is no logic on this and nothing in the movie warrants this...

"investment"????....lol...o_O....they ddnt waste money...we arent paper product...its a difference in me creating nano machines to do specific task and creating or inventing money that smells like chocolate that losses value the second it leaves the mint......humans....dont until they are old.........we werent wasted investments.....aparently 1) we were at some point used for the hunts one earth and 2).....we lived long enough to make too space to see the JOckeys in person....the Jockey itself was suprised to see humans when it woke up...its just even tho this is not a pre-quel....(lol...ha..) WE know...as fans that U absolutely have to tie US, The Jockeys, and Predators together......and again think abt this....would u rather die and hope ur nano machines(humans) tht u put ur blood and sweat and time into creating thrive or ur chocalate money survive after ur died??....

jesus........it.....is......impossible......to read.....that......... AVPHUNTER........fix yourself.

AvPHunter, sorry but this time I can't get your post...I really can't get the meaning of the text. I need to improve my english it seems... oO Well, on the post that based that answer (of sorts) the thing is, investing your time and resources for a million or a billion years for that reasoning is really...well...strange to say the least. I seriously doubt such a concept would even make into a pure action movie, least something that is supposedly to go epic... I plant some cells on a pond and I will wait a billion years to use my fishing rod on the results...well, I better have a really good book with me...and a thick one at that XD

LOL....good one Hawk...i like that...
