We know how it crashes, but how does a Derelict land?!

Okay so I don't think anyone here has yet argued that the Derelict in both Alien and Prometheus does [i]not[/i] crash land. Afterall, in Alien and Aliens it looks like it's toppled over and also ruptured, and in Prometheus it descents after an explosion caused by a possible collision mid-air. But suddenly I just thought, "wait a minute, what if in one of the two films, the Derelict is in fact landed in the correct position?" For me, in the Prometheus 'crash', surely it is far more difficult for the ship to crash upright as it were than it is to come down, wobble around, and fall flat on its face? We can all try it with any coin in your pocket - I bet none come to rest edge on... Right? I'm now more leaning towards the ship doing an emergency landing which also happens to be the correct landing position, hence the not too much damage to the ship (debris is from the collided impacter) - now ok we don't see any landing gear or equivalent but maybe that's just alien technology for you. However... Although this theory pleases and satisfies me, ironically it's the Derelict in Alien which provide a counter argument: the end state of the Alien Derelict is not edge on but more slanted like its fallen on its back. It looks crashed to the human eye but perhaps this one is not crashed but landed as best it could. And the reason I raise this is because of the cockpit/SJ room and the eggs chamber. You'll notice that both are flat against the surface of the planetoid, which would lead you too assume landing with correct orientation. Moreover, the eggs are in pristine condition - none have tilted or toppled over or look as if they've shifted due to... oh I dunno, a ship crashing down!? So what [i]is[/i] the normal way a Derelict would normally land? - because it could be that one of the two 'crashes' is actually a textbook landing.
