We've already seen the Dragon capsule successfully take off, and hover, but its the part where it plummets to earth that its human cargo will likely be most concerned about. The recent tests passed without incident, but more rigorous trials are still needed. When astronauts are coming home from the ISS, their capsules will actually land on water. But, with the hover test complete, and more parachute testing planned, the ultimate goal is to put those SuperDraco engines to use, and bring capsules safely back to terra firma directly.
