The reusable rocket booster was an amazing accomplishment.
Here is a video of the first successful land recovery, when you consider where this rocket was when it began its descent, the successful recovery let alone the pinpoint accuracy, is nothing short of slack jaw amazing.
Now they are taking the second step to recover even more of the rocket for reuse. The clam shell covering, known as a fairing that protects the payload that is ejected just prior to orbit, will be recovered,
the animation,(<--link), of what they come up with made me laugh, but you gotta give it to them, it is actually brilliant. Rough seas may make it more difficult though.
Question authority. How do you know, that you know, what you know?
