Circular Engineer Ship

I was intriqued by this scene in the trailer as well. Doesn't seem to be much mention of it though. Is it a craft? Looks like your classic saucer shaped UFO. Don't know what make of this as it doesn't appear to tie into anything else we've seen so far ....... If indeed it is some sort of ship.

idk why but i always thought of space jockey technology to be biologically based, as in they do not build there ships, they are "grown" kind of like the tardis from doctor who. if that is true then all of them are different, so that was was a weird alien harp looking thing and this one is a more classic looking saucer.

I agree, I think this is the engineers terraforming Earth - seen at the beggining of the film.

whats more intriguing i think is the little ship seen zooming across the screen at the beginning of the trailer...[img]http://www.avpgalaxy.net/gallery/albums/movies/prometheus/trailers/normal_20111222_teasertrailer03.jpg[/img]
