Would DAVIDS head & body still be in the same place after crashlanding in the sp

Fair question. I suspect the answer is the good old boring, "it didn't matter for the story where in the room his head and body ended up, so no need to bother with that too much". In any case, the control room inside the Juggernaught isn't too damaged when Elizabeth gets there a second time. Which is quite a feat, since it survived not only an impact with a ramming spaceship, but also a fall from several hundred meters in the air. On one of its horns, no less. And an 'open' doughnut is a very fragile structure, there'd be lots of stress accumulating right in the center of the doughnut.

David's head and body were not in the same place as they were after having his head ripped off. It started on the platform near the 'Giger Gun' and Shaw finds him over on the floor, randomly placed. Seems like he probably did bounce around quite a bit, actually.

Yes Probably. But wouldn't his body be smashed up near and beyond repar? It would have rolled around endlessly in that room like a hampster in a plastic excersise ball! The same for his head, both parts of him would possibly have fallen into the spaces above the Chairs when the entire craft was tumbling on its side so its just a thing I wondered about.

Consider: the Juggernaut would probably have had some gravity generation, perhaps advanced enough to act as a shock absorber to the extent that little changed or was felt when it was struck, or when it crashed. Also, given how slowly it came down, and didn't throw Shaw or Vickers from their feet when it hit the ground, or squish Shaw to a pulp, could it be that it weighed very little at that time? That maybe part of its lift off routine was an alteration of gravity around the hull itself?

as fleshvessel said, davids body and head are not at all in the same place. As to why they were not destroyed...why should they be? we dont know the materials used in david 8's construction.

".. that it weighed very little at that time.." Speaking about the Juggernaut I had not thought about the weight of the actual ship.(perhaps I should seek out a thread on the Engineers' ship) If through millions of years of developemnt the Juggernaut material could be strong and lightweight then this would be an ideal traveling design. What if the outerskin weighed less than a piece of paper of the same is this even possible? If it is too light then it could not have survivied the sand storm the Ptometheus faced. When the Juggernaut hits the ground there should have been a thunderous sound/shock waveand then the rolling begins. I'll have to review that scene again to see how RS depicted the 'landing' of this alien space ship. It may be properly depicted but I can only visualize the ship crash landing and start the rolling process.

youd imagine the room would be designed to correct its position like one of those balls that have an unevenly weighted core that spins within the outer shell so its always up right when the ship is subject to gravity so the occupants of the chambers dont get rattled about (saw no restraints) however he does seem to have moved and deleted scenes appear to show bob leaping down a tilting platform so maybe he did get thrown about i didnt see the other bodies but then hed roll back roughly toward the middle more easily than they

It is amazing how much room there was in the Juggernaut(and even the Prometheus) when the earth's space capsules were so small. cramped and really closed in. The size the rising chair moving up fom the floor into the spacious orrery is quite impressive. I didn't select this part of a movie as a favorite scene but I can understand other did. For an earthling raised on small is needed space program the spacious future space ships look quite inviting..

Future spaceships- FTL ones in particular- are magic, so sensible rules of design need not apply. Proportionally speaking though, it appears to me that the Prometheus was more spacious than the Juggernaught. I can't say I really have a case for why I believe this, only very flimsy arguments. One is that the layout of rooms inside the Juggernaught, that we see in the holographic mapping, has a few large halls, granted, but surrounded by incredibly thick walls. Whereas, the Prometheus appears a lot more flimsy in construction. They even have glass windows looking outside.

In the FTL world would the spacecraft design have any bearing on it's final look? By than I mean if a ship was round, square,oval Cube ect would it really affect the travel to distant worlds?

If you want to, yes. If you don't, it doesn't have to. There's nothing in physics to say, "FTL ships must be so and so" (apart from, 'impossible', but whatever :P). So if you are an author and want to write about, or make films about, FTL ships, really, do whatever you want. As long as you're consistent, you're fine. In the kind of space travel we know of, for example, the shape of the ship is only indirectly important. It doesn't have to be aerodynamic because there's no air in space, for one. There will likely be large radiators at some places, usually near the engine/power plant. It also appears, but opinion is disputed, that a trailer-type ship of the kind seen in Avatar can have less structural mass, and therefore be more efficient. I speak of pure spaceships here, a vehicle designed to take off from/return to the surface of a planet would do well to look aerodynamic. But it would be very inefficient to have a vehicle capable both to lift off a planet and do interstellar travel, oddly enough. The kinds of engines useful for those two tasks tend to be rather different. And of course in a real ship space and cargo capacity are at a premium.

@Corpo What do you know of RCS thrusters? Prometheus engages these thrusters as it's landing but it's my understanding the RCS thrusters have very low thrust and are only used in space for orientating procedures, for example, docking.

Depends what you mean by RCS (reaction control system). The Space Shuttle uses ... uhm, used ... them for maneuvers in space, as they aren't anywhere near adequate on their own for things like liftoff. That's not their purpose, as you say. The Harrier Jump jet uses them for stabilization in maneuvers at low speed, quoth wikipedia. In other words, for stabilization in maneuvers like the Prometheus performed on landing, and I believe that's why that got in the film. EDIT: There was another thread where one poster (not me, oddly :) ) commented that ion propulsion is a weird thing to activate when doing ramming maneuvers. Ion thrusters, at least today and in the foreseeable future, are intended as high exhaust velocity engines, which implies good fuel economy for high delta-V budgets (an ability to switch between vastly different orbits), but low thrust.

2 different ships. The bridge obviously can control any of the many "david" ships. The ship Shaw and David go on searching in isn't the crashed ship either.
