" Don't tell me it can't be done", that's what the president told his crew. The possibility of "can" or "can't" is simpliy defined by one's heart desire. When you're on your own, it comes down to the choice of black or white and you just need to stand on your ground till mission completed. The cruel fact aknowledged is that you can't once more back up and redo it. You just have to pass this one-way street find your way out. I like Mike's interpretation: it's impossible but doable.
