I watched the launch online via the SpaceX web stream.
After the booster stage landed back on land, they mentioned that eventually more and landings on land would further their goal of getting to a 24 hour turn around for boosters.
Imagine, launching one day, landing the booster back on land, loading new cargo on it and launching it again the next day.
Now that is incredible.
Range safety dictates if its going to be a land or water landing for the 1st stage out of Florida — will always be a dry landing @ VAFB due to earth rotation and most launches out of there are going into a polar/sun-synch type of orbit. I do recall the commentator talking about the 24 hour turn around as the refab facility is within a couple hundred meters of the landing pad. Cool times we live in!
