So the derelict crashes

Good questions - I think it crashes BECAUSE a facehugger got out! Sabotage perhaps?

^oooo hey thats good idea

the big trunk guy was a brve warrior, he was transporting them away from is kind and his ship runs out of petrol then crashed on lv. along comes ripley and crew and then im stuck...

I've said it before, ship crashes due to SJ chest burst. Only way to tie it all in.

yeah but wouldnt the jockeys know about the chest bursting and shouldnt that one jockey be in his ships med lab..you would think if they engineered the xenos...or used them as weapons they would know that if a face hugger attaches itself to you then you need to have the embryo removed i think there might be some continuity problems because in alien the jockey was the alien and it had fossilized then ridley changed it to a biomechanical suit...that means the face hugger had attached itself to somoene before they go inside the suit as opposed to a face hugger attaching itself directly to the head of the bio suit

I have a hard time imagining that little chestburster bursting out of the Space Jockey's massive sternum. Unless it waited until it was mature enough to force its way through. Still, looking at the Space Jockey's "helmet", the facehugger must have had a tricky time getting its penis inside of the Jockey's mouth to lay a larva in the SJ's chest. What with that hose running from the Jockey's nose down across his chest... Although that hose could have been attached after the facehugger withdrew from the Space Jockey and scurried away to die in a dark corner. So that hose we see wasn't attached to the Space Jockey the entire time he's in his chair? Maybe the Space Jockey was attacked by a facehugger before he gets into his chair. The SJ grows into his chair, attaches a hose to his nose, the chestburster punches its way out of SJ's chest after maturing for a couple of months. Now it makes sense.

If it doesn't happen during flight, look at pre flight and post flight. Pre flight why would he be in chair - if chair is for the pilot? Thats asumming it is a pilot chair. How would it take off to crash? Post flight makes no since. If the ship has crashed and will not fly, why would he be strapped in?

we shoot it down and thus cause our own fate.

First, you are all assuming the facehugger introduces the alien 'seed' into the SJ the same way it did with humans. This is because that is the way we were taught in 1979. What if there is another way for the alien seed to get into the SJ? How many orifices does an SJ have? To answer this you need to know what the SJ is - and nobody does definitely. I have my own theories, the word 'seed' playing a key role... I think we may be shocked by what RS comes up with. He is inventing a new universe here. They are already making the [url=http://www.prometheus-movie.com/news/109]toys[/url] ... I want the life-size SJ for my Birthday!

hmm^ interesting points..im going to goahead and bet that the face hugger implanted itself in the usual way regarding the space jokcey based on the exit wound in the bio suit near the chest...and we do know that the space jockeys are bipedal with 2 arms 2 legs....2 eyes....and a nose or a mouth judging by the trunklike hose...im guessing the face hugger got in through the mouth...and come on the space jockeys gotta be humanoid...theyre tall theyre blue they created us in their image...look at the annunaki
