That's true about number 1. I'm no physics buff but I know get what you're saying. I guess the Mako did crash though =/ I wouldn't call it a plot hole so much as what you said, a physics hole or simply chalk it up to the tropes you need to continue a story. Basically what you're saying is that Shepard and co should have been dead and well, we can't have that.
