The fastest thing that's ever been built is the New Horizons space probe which is currently on its way to Pluto, it can travel about 36000 mph, at that speed it would take it about 750,000 earth years to get to these planets, it puts current technology beyond the scope of travelling to the stars me thinks.
An FTL spacecraft is a pipe dream thought up by some hare-brained scientist with too much time on his hands, by the time anyone could work out how to build one of these things the human race will either be dead or they'll be back in the trees where they belong.
