This is not a far fetched idea some scientists say. With the much advancement in Aeronautics, it is quite possible for this to happen. NASA has not said whether or not this is ever going to be possible and many have said that this is a Trekies dream. But is it possible? That question has yet to be answered correctly. It is possible if you asked people living in the 15th Century if there were going to be two story homes and electric cars in the 21st Century they would have laughed and called you crazy. Many have also thought of this tactic when confronted with hotels on the moon in 2015. But it is plausible.
