Was lv 426 well past volcanic activity ? Was volcanic activity something that has long since been non existent ?

Well, according to James Cameron, volcanic activity was the reason for the derelict's damaged arm in ALIENS. 

OK

So the derelict was never destroyed by volcanic activity ??

Does aliens at any stage show this damage in the movie ??

Yes, during the scene where Newts mum and dad enter the derelict.

It's interesting to note that the juggernaut in Blomkamps concept art doesn't have a damaged arm. So, is that the jugg from Prometheus?

Never actually noticed that before.

 

Thanks a lot necronom 4.

Does this imply that alien and aliens aren't canon as ash's statement contradicts what happened in aliens or was ash lying ? I remember geysers blowing steam into the air.

I am going with ash lying.

"It's interesting to note that the juggernaut in Blomkamps concept art doesn't have a damaged arm. So, is that the jugg from Prometheus?"

Great question

Wow  that opens up a whole lot of possibilities ??

IL be glad if it is

Well spotted and well noted necronom 4

I don't think ASH was necessarily lying. I think it's more likely that Cameron didn't do enough homework before he created ALIENS.

Is this possible grounds for dismissing aliens as canon ??

Well, there was no explination given for the damage in the film. James Cameron gave that explination in the ALIENS documentary, so it is left open to explination in ALIEN 5, if that's something that Blomkamp wants to explore.

thanks necro

With the greatest respect Odu, I've always  thought Ash said 'Deep coal, well below the line".

That's why Kane's ears pricked up, and he volunteered to be in the first group to go out, thinking there may be mining opportunities to be had?

Anyway....whatever unknown material the derelict and Juggernauts are made from, I think it can withstand just about anything.

The Derelict from ALIEN may have been on LV426 for thousands of years or more, and had no obvious damage. The Juggernaut in Prometheus hardly sustained any outer damage, even after a direct hit from the Prometheus plus it's ion propulsion engines exploding!

according to the script it was "cold".

Gah, I really need to have my hearing checked....all these years thinking he said coal! 

In the ALIEN Full Colour Movie Novel it's "coal", but the Illustrated Screenplay and The Illustrated Story both have "cold". 

....mucho apologies Odu! :)
