This recent interview has Musk quoted and making it explicit and clear that SpaceX has not yet succeeded with reusability, despite a number of attempts. [http://www.askmen.com/entertainment/right-stuff/elon-musk-interview-2.html Elon Musk Interview], at ''AskMen'', published in April 2014.

Also has this Musk quote describing the process of getting reusability to work:

<blockquote>"Expendable rockets, which many smart people have worked on in the past, get maybe 2% of liftoff mass to orbit -- really not a lot. Then, when they’ve tried reusability, it’s resulted in negative payload, a 0 to 2% minus payload [laughs]. The trick is to figure out how to create a rocket that, if it were expendable, is so efficient in all of its systems that it would put 3% to 4% of its mass into orbit. On the other side, you have to be equally clever with the reusability elements such that the reusability penalty is no more than 2%, which would leave you with a net ideally of still 2% of usable load to orbit in a reusable scenario, if that makes sense. You have to pry those two things apart: Push up payload to orbit, push down the mass penalty for reusability -- and have enough left over to still do useful work." </blockquote>
