So, in ME1, the Mako comes flying out of the Conduit and crashes on the Citadel. But it's never really explained why that happened, other than a theory that it might preserve the momentum of the object or person in question. Essentially meaning that if you're driving 60mph when you enter, you exit at the same speed. And it's not known if the point where the object or person exits at is the same, or determined by the Conduit itself. It would be quite harmful if a person came through the other side several feet in the air and dropped to the ground suddenly.

But, from game lore, we're told the Prothean scientists successfully got through and that Saren also got through without any noticeable problems. So, I think there's at least one possible theory to explain it. The most likely answer for me is that it normally does not preserve the momentum of anything that passes through it, and that it can determine where the object or person exits from. Normally, the person or object would be transported to the surface of the Presidium, exiting with absolutely no momentum. But once Saren got to the other side, he disabled these "safety features" so anyone or anything coming from Ilos would get flung upwards and crash back down. At best, the traveler or object would be injured or damaged, or be killed or destroyed at worst.

What do all of you think?
