New Movie Trailer

[Jak Nazryth]

Sorry if this thread might not belong here, but I was COMPLETELY surprised by this.
Stumbled across this by complete accident. I had NO idea this movie was even in the works.
Just to let everyone know, the reason I stumbled across this was when I was trying to google how FTL travel happens in this series of movies. I know it's different from Traveller, but does anyone know how it works? Besides hypersleep chambers that is...
Here is one cool trailer...

I have the Colonial Marines Technical Manual, and there's a section in there about how the hyperdrive works on the Sulaco. I don't recall the exact details - it's basically the sort of mumbo jumbo you'd expect ;-) I do recall the fusion reactor uses lithium as fuel though, I think because it's easier to store on a military vessel than hydrogen.

I also have the Alien Vault, which has a technical drawing of the Nostromo. According to that, the Nostromo has a Yutani T7A NLS tachyon shunt supra light drive, and can achieve an unladen speed of 0.42LY/day (or 153c), but only 0.1-0.12LY/day (40-45c) when towing the refinery (as we see in the film). The ship has 14 months standard, or 24 months extended, duration.

I think from that you can deduce that FTL in the Aliens universe is dependant on mass - the more mass you add to the vehicle's cargo the slower it's FTL speed. Also, the unladen speed of the Nostromo is almost exactly the same as Jump-1 Traveller (1 parsec/week = 3.25LY/week. 3.25 / 7 = 0.46 LY/day) - the main difference is that ships in the Alien universe can just keep cruising along for months at a time. Settled worlds seem to be far more sparse than in the Traveller universe (probably more realistically).
