Um, ok, first of all, get a grammar checker.
Second of all: Why be a miner if there's no point in the story? Not only is that pointless, but it doesn't make any sense: some down in the dirt miner suddenly becomes the top pilot of the GTVA cause he found some old device? Nuh uh, it doesn't work that way.
Also, if the GTVA was completley boned financially, it's possible that they would have built another collossus, but why? It took four years or something to build the first one...why spend their limited money on another juggernaut when the last one got pasted by the Sathanis?
And where exactly were you when you "go out"....are you saying you are stationed on the Capella, then, it disintegrates, but you're still inside of it...yet you then go out after it disintigrates, and then look at the wreckage? What?
And I'm not even gonna go into the last part.
Not to be cruel, but you really need to work on that storyline.
