Okay so the bio-weapon outbreak occured in the Engineers spaceship that the Prometheus's crew found when they 1st landed on the planet.

In the Engineer spaceship, all the engineers was found dead except for one survivor (who later died after got tentacle rape-ed by Shaw's octopus baby).

Then at the ending, David offered Shaw for his help to seek another engineer spaceship because he mentioned that there are also a few spaceship similar to the one they found. And then we saw another engineer spaceship fly to the space with probably Shaw and David in it.

My 1st question is, did ALL the engineer spaceships in the planet had occurred the same outbreak same as the 1st engineer spaceship that the crew encountered? Because I found it funny that they required a lot of time to figure out what happened on the 1st spaceship but then it just took 1 minute for both Shaw and David to infiltrate another spaceship and fly it like nothing happen.

2nd question, if there's already an outbreak on the planet, why the heck that no help comes from the engineer's home planet to rescue. I mean, they are the superior race that monitor all life in the universe and yet they didnt sent any rescue team when outbreak occured. I mean, its look funny when the planet is abandon for 2000 years whilst nobody from the engineer's home planet found it strange like "why is it no one from our military base havent given any reports?"

My opinion is Charlie shouldnt be allow to die. From the 1st 1 hour I admire that he's a cool character including that scene where the medical team examining the engineer's head, he just sit there and drink wine and after it exploded, he just walked away like nothing happen. Probably the director think that somebody from the expidition group need to trigger something and he's very unlucky that he's the 1st person that David met when David is searching for his potential 'lab rat'. Same goes to Vickers, dunno why the director killed her character because I do assume that she can replace Ripley in terms of her charisma and ego. Now I do hope that if there is a sequel, she suddenly survives the 'donut' attack like Shaw did and went back to earth for reinforcement.(sigh~)
