Even though by now I'm used to seeing the first stage of a Falcon 9 land with pinpoint accuracy on a barge in the middle of the ocean, I still can't believe that this is actually going to be attempted. It seems like the cost of failure would just be too high - replacing or repairing the tower is going to be very expensive if anything goes wrong. That being said, I've enjoyed the process of having my expectations of what's possible repeatedly shattered over the last few years by SpaceX, and I hope that it continues for a long time.
